'I did not rear you to be killed in an airplane,' she said. 'Join the navy.' He took her advice and in doing so determined his future. In small patrol boats, Fairmiles and a Harbour Defence Motor Launch, he patrolled the shores of Japanese-held territory, assisted beleaguered commandos in Timor, and was finally caught up in the drama of rounding up Japanese prisoners of war and guarding them in New Guinea.world war 1939-1945 - naval operations - australia, royal australian navy

Index, bib, ill, maps, p.476.non-fictionHMAS Sydney's hunt for the German raider, Emden. When the ships of the new Royal Australian Navy made their grand entry into Sydney Harbour in October 1913, a young nation was at peace. Under a year later Australia had gone to war in what was seen as a noble fight for king, country and Empire. Thousands of young men joined up for the adventure of having 'a crack at the Kaiser'. And indeed the German threat to Australia was real, and very near - in the Pacific islands to our north, and in the Indian Ocean. In the opening months of the war, a German raider, Emden, wreaked havoc on the maritime trade of the British Empire. Its battle against the Australian cruiser HMAS Sydney, when it finally came, was short and bloody - an emphatic first victory at sea for the fledgling Royal Australian Navy. This is the stirring story of the perilous opening months of the Great War and the bloody sea battle that destroyed the Emden in a triumph for Australia that resounded around the world. In the century since, many writers have been there before Mike Carlton. Most were German, some of them survivors of the battle, others later historians, and they have generally told the story well. British accounts vary in quality, from good to nonsense, and there have been some patchwork American attempts as well. Curiously, there has been very little written from an Australian point of view. This book is - in part - an attempt to remedy that, with new facts and perspectives brought into the light of day.world war 1939 – 1945 – naval operations - australia, world war 1939 – 1945 –naval operations - germany

The painting was donated to ANZCA in 1995 by Dr Bernard Dunn. Bruce Fletcher, from Melbourne Victoria, studied under William Dargie, who had been an official war artist during the second world war. Fletcher followed the same pathway as his mentor and was the first of two official war artists appointed during the Vietnam War. His artwork are held in the art collection of the Australin War Memorial, Canberra. The title of the painting, 'Dust Off' is a term adopted in Vietnam which refers to the medical evacuation of sick or wounded soldiers, from the field, by a helicopter. It was originally a radio call sign selected from a US Navy Signal Operations book in 1963. [ref. 'Medicine at War. 1950-1972'].In June 2012, a Royal Children's Hospital Anaesthetic Registrar attended a College Tour conducted by Dr Rod Westhorpe when he saw the painting and informed us that the term 'Dust off' emanates from the Korean War and is in fact the acronym for Decisive, Unwavering, Support to our Fighting Forces'. The painting was based on a black and white photograph taken in Vietnam in 1971. An image of the photograph is located in the electronic supplementary file.

Operation Hammersley , 10 February until 9 March 1970, was undertaken by a combined force of: C Company, 8th Battalion, the Royal Australian Regiment (8RAR); armoured personnel carriers from 3 Cavalry Regiment; tanks from 1 Armoured Regiment; sappers from the Royal Australian Engineers; a mortar section from 8RAR’s Support Company; air support, and even a Navy destroyer off-shore to provide gunfire support. The operation aimed to protect 17 Construction Squadron, Royal Australian Engineers, at a quarry in the western foothills of the Long Hai hills. The Long Hai hills were a stronghold for the Viet Cong, who used the caves there as a bunker complex and had planted many landmines and booby traps in the area. Over two fierce weeks, 8 RAR carried out patrols and conducted ambushes, engaging VC troops and eventually capturing the bunker system. However, it was a costly campaign. In total, over 70 Australians were killed or wounded during the operation. The worst day for mine casualties in Australia's war in Vietnam occurred on 28 February 1970. It became known as 'Black Saturday". Nine members of 8RAR were killed and 29 wounded. This item is the Order of Service from the memorial service held at Nui Dat on 3 April 1970 to honour those killed at Long Hai. It was issued to the donor, National Serviceman G G Ravenscroft, who was serving in 1 Platoon, A Company 8RAR during Operation Hammersley, and received a minor shrapnel wound on Black Saturday.Two typed A-4 pages that have been folded into booklet, now flattened and framed.

M1 Steel helmet used onboard HMAS Kanimbla. These M1Steel helmets were first issued in 1941 to the United States Armed Forces. They were adopted after the Korean War by the Australian Defence Force. In the 1990s they were replaced by the Kevlar based Personnel Armour System-Ground Troop (PASGT) type helmet. However, as evidenced by this helmet, some M1 Steel helmets were not replaced in-service by the PASGT helmet and survived into the early 21st Century. Interestingly, the Nato Stock Number (NSN) printed on the inside of the helmet liner indicates that this helmet was made for a Bulgarian contract, as evidenced by the NSN National code of 50 in the second group of numbers in the stock number. HMAS Kanimbla (LPA-51) was built for the United States Navy as USS Saginaw and was launched on 7 February 1970. Kanimbla was commissioned into the Royal Australian Navy in August 1994. Kanimbla was heavily involved in Operation Slipper conducting a variety of tasks such as patrol, mine recovery. During Operation Slipper, Kanimbla also conducted 27 compliant boardings and 23 non-compliant boardings in the Persian Gulf in 2001-2.Standard issue United States M1 pattern steel helmet, olive drab in colour with liner.

With the outbreak of the First World War, HMAS Australia became the flagship of the naval force that captured the German colonies in the southern Pacific. She led a force which captured Rabaul on 13 September 1914 before proceeding to Samoa. With no German forces left in the South Pacific, Australia was deployed to the United Kingdom. En route she sank the German ship Eleanore Woermann. On 8 February 1915 she became flagship of the 2nd Battle-cruiser Squadron of the Royal Navy's Grand Fleet. Australia's service with the Grand Fleet consisted of a series of frequent patrols and exercises. She was twice rammed, firstly on 22 April 1916 by HMS New Zealand. This led to her missing the Battle of Jutland which, considering the disastrous losses in the Battle-cruiser Force, may well have been fortunate. She was rammed again by HMS Repulse in December 1917. Australia carried out experimental aircraft operations in 1918 and led the port column of the Grand Fleet at the surrender of the German High Seas Fleet. Returning home in 1919, Australia suffered a mutiny upon reaching Fremantle, Western Australia. Quite obsolete, she became a training vessel in Westernport until scuttled off Sydney Heads on 12 April 1924.The Australian Navy's first flagship, the battle cruiser HMAS Australia (I) was the centrepiece of the 'Fleet Unit', whose acquisition signalled the RAN's arrival as a credible ocean going force. Ordered from John Brown and Company in March 1910, construction began three months later with the total cost of the ship and fittings expected to be some £2 million. The Commonwealth Government decided upon the name Australia, and it proved a popular choice, carefully avoiding any suggestion of favouritism towards any one Australian State. The ship's badge maintained the national theme by featuring the Federation Star overlaid by a naval crown, while the motto 'Endeavour' reflected the ideal of the Australian spirit and recalled Lieutenant James Cook's ship of 1768-71.Timber frame of black and white print of a ship at sea.Imperial War Museum Photograph HMAS AUSTRALIA - RAN FLAGSHIP First flagship of the Royal Austrlian Navy 1913-1920 Sunk under the terms of the Washington Treaty 12th April 1924 This frame is made of teak from her deckhmas australia, ww1

In 1949 the HELLENIC PRINCE with its 3 hospitals, 2 cinemas, and air conditioned accommodation was chartered by the International Refugee Organisation to transport displaced persons from Europe to Australia. Its first trip was to Sydney where it arrived with 1000 passengers on 5 December 1949. On the third trip it left Naples on 23 March 1950, and arrived in Fremantle on 20 April 1950, and in Melbourne on 25 April 1950. The men and women were separated for the voyage with my father sleeping on a hammock in a large room with other men, while my mother, my brother, and I had bunks in a shared cabin. On board were displaced persons ex Bagnoli Camp Italy, some of whom later built their bungalows on the grassy and rocky paddocks near Sunshine Victoria, and began to establish a new life in a new country. A few of the families that arrived on the third trip and purchased land in the Dunkeld Ave - Sandford Ave area of North Sunshine (Birmingham Estate) were Janczak, Kolanowicz, Mroz, Pawlak, Rasztabiga, Skrobalak, Szydlowski, Witkowski, and Zielinski. Some friends settled elsewhere in Sunshine. The family Tabaka went to West Sunshine just over the Derby Rd Bridge, while the family Wojcik went to Ardeer. The ship first started service in 1929 for the Royal Australian Navy as the HMAS ALBATROSS. It had a standard displacement of 4,800 tons and was 443 feet 7 inches (135.2 metres) long, and its top speed during trials reached 22 knots (41 km/hr). It was built at Cockatoo Island Dockyard as Australia's first Aircraft Carrier (seaplanes), but the aircraft that it was designed for were retired just before the ship went into service. A new plane specifically designed to work with the Albatross began operations after the ship was decommissioned in 1933, and placed into reserve in Sydney Harbour. Seaplanes continued to operate from the anchored ship. (Click on the Link 'HMAS Albatross (1)' situated above the Object Registration number to view pictures of the HMAS Albatross on the Navy web site). In 1938 the ship was recommissioned and transferred to the Royal Navy as part payment for the light cruiser Hobart. The ship then did military service for the Royal Navy during World War 2. It did patrol and escort duties in the southern Atlantic, and from mid 1942 in the Indian Ocean. By early 1944 the ship was converted so that it could repair landing craft and other support vessels off Sword and Juno beaches. The ship managed to return 132 craft into service and to save 79 others from total loss. On 11 August 1944 Albatross was torpedoed with the loss of either 50 or 66 personnel, but was able to be towed back to Portsmouth. After repairs she did a short service as a minesweeper depot ship, and following that was placed into reserve on 3 August 1945. In August 1946 the ship was sold for commercial use but the plans to convert it into a luxury liner or a floating cabaret fell through. The ship was again sold on 14 November 1948 to the British-Greek Yannoulatos Group, who renamed it HELLENIC PRINCE in recognition of the birth of Prince Charles and his Greek heritage. After conversion into a passenger ship the Hellenic Prince made several trips to Australia transporting displaced persons, however apparently not all trips were pleasant for the passengers. In the on board newsletter 'Kangaroo' dated 5 January 1951, the ship's master P. C. King expressed his indignation about the behaviour of passengers and made accusations of mutiny. According to some immigrants the conditions were appalling and overcrowded with 1200 passengers. Passengers were supposedly required to work and were paid with Woodbine cigarettes. The drinking water ran out, the freezer broke down, and fresh food that was brought on board went to the crew. Sea sickness was rife because the ship was rarely level due to malfunctioning pumps. (The newsletter 'Kangaroo' can be viewed at the Museum Victoria web site by clicking the Link 'Newsletter - Kangaroo'). In 1953 during the Mau Mau uprising the Hellenic Prince was used to transport troops to Kenya, and in 1954 the ship came to an end in a scrap yard at Hong Kong. THE ABOVE INFORMATION WAS COMPILED FROM; (1) http://en.wikipedia.org/wiki/HMAS_Albatross_(1928) (accessed 11/2/2013), (2) An article by Graeme Andrews found at http://www.afloat.com.au/afloat-magazine/2011/july-2011/The_boat_people_of_the _forties_and_fifties#.UuYY6ou4apo (accessed 27/1/14), (3) http://museumvictoria.com.au/collections/items/273166/newsletter-kangaroo-hellenic-prince-5-jan-1951 (accessed 27/1/14), (4) National Archive search starting at; www.naa.gov.au/collection/search/index.aspx (accessed 27/1/14), (5) http://www.flickr.com/photos/41311545@N05/3864781978 (accessed 29/1/14). Hellenic Prince has a significance to Sunshine Victoria because some of the displaced people from Europe, who arrived in Melbourne on Anzac Day 1950, were among the first people to settle in the grassy and rocky paddock areas of North Sunshine. These settlers established a residential suburban area out of the paddocks. In those early days there were no services and the planned roads were basically just drawings on a map. The ship is also significant because it was named in recognition of the birth of Prince Charles. In the ship's former life as the HMAS Albatross the significance is that it was built in Australia as our country's first Aircraft Carrier (seaplanes).New photograph made from a scanned copy of a circa 1950 Post Card featuring the ship on calm water.Hellenic Prince / Hong Konghellenic prince, migrant ship, displaced persons, refugees, international refugee organisation, bagnoli camp, hmas albatross, yannoulatos group

In the evening of 20 November 1940, while en route from Queenscliff to Portsea in Port Phillip Bay where she intended to anchor for the evening, she collided with the 10,364 ton, outward bound passenger liner, MV Duntroon, which struck her amidships on the port side. Duntroon’s captain had believed that she was on a parallel course to Goorangai and overtaking her. By the time he realised Goorangai’s true course, with Duntroon travelling at more than 17 knots, it was too late to avoid the collision. Goorangai was cut in two and sank in less than a minute with the loss of her entire crew of 24. Just six bodies were recovered in subsequent salvage operations. She was the first ship lost by the RAN in World War II.This event is still remembered by the community at an annual ceremony in Queenscliffe.

An incomplete diary of an Australian nurse serving in France in 1916. The author is unidentified in the document but after extensive research it is concluded that is by Priscilla Wardle, who left Melbourne on 14 April 1915 on RMS Orontes and served with Queen Alexandra's Imperial Military Nursing Service (QAIMNS) in France. A larger portion of her diary is available from the Ballarat Base Hospital Trained Nurses League entries on Victorian Collections. The contents of the diary has been retyped and is in the Word document. The diary shows she was serving at a Casualty Clearing Station (CCS) in Bethune, France in March 1916. She goes on to serve at Wimereux, at the No 8 Stationary hospital. Also possibly at Boulogne. She had a period of rest at Hardelot, a convalescent home for nurses, and also a trip to England and Scotland. She tried to visit the graves of ancestors, such as relatives of 'Grandfather Allan', in the church yard at East Kilbride church. During her nursing experience she mentions being gassed by 'weeping' gas and hearing the sounds of shelling. Also the numbers of operations per month, such as 311 in March 1916. And another day when there were 29 operations in one day. She talks of POWs coming to the hospital. They are treated after the Allied soldiers are looked after. So operations often continued into the night to take care of the Germans. She also mentions removing a piece of shrapnel herself in one operation. She appears to be of a senior rank as she is asked to meet with senior hospital officials and high ranking officers that visit. In particular she mentions a staff surgeon from Admiral Jellicoe's ship the 'Iron Duke'. He visited just after the Battle of Jutland, which was a naval battle fought between Britain's Royal Navy Grand Fleet, under Admiral Sir John Jellicoe, and the Imperial German Navy's High Seas Fleet, under Vice-Admiral Reinhard Scheer, during the First World War (‎31 May – 1 June 1916). Also being visited by Stan Walker (also from Ballarat) and Lt Brough who was ADC to General Legge. It is possible Stan Walker is Lt (later Captain) Edward Stanley Walker. Lt Brough is believed to be Charles Anthony Brough. She also mentions meeting a Lady Gifford and Madam O'Gorman. She mentions travelling with Captain Newton to London in early December 1916 - she calls him Sauchiehall and Sauchie, both could be nicknames. Capt Newton later becomes Sir Wilberforce Newton, who was serving in the Royal Army Medical Corps on the Western Front between 1915 and 1917. His diaries are held in the University of Melbourne archive. He also left Melbourne on the RMS Orontes on 14 April 1915 (source Trove) and would have known the 14 Victorian nurses that went on to serve with QAIMNS. On 11 December 1915 he mentions trying to see a Sister Loughran at the No. 7 Stationary hospital - which was in Boulogne. Sister Loughran was also on the RMS Orontes. When he was ill he mentions receiving a parcel from two other nurses that were on the Orontes and served with QAIMNS (Madge Donnellan and Margaret Donaldson). Other things that indicate it might be Priscilla Wardle is that from Births Deaths and Marriages Victoria (BDM) she was born in Ballarat, her mother's maiden name was Allan, she had a sister Janet that went by the name of Jean who was married at the time mentioned in the diary (BDM and Trove), Priscilla's mother also died during the time of diary and coincides with the diary entry of the 'death of dear mother'. An article in Trove after Priscilla's return to Australia mentions she was in the areas mentioned in the diary. Also that Priscilla went on to be trained as an anaesthetist to help in the surgeries. It matches the comment in the diary that she was involved in many operations and even allowed to perform a bullet extraction. Finally on seeing the diary held by Ballarat Base Hospital Trained Nurses League - it was determined the handwriting matched and this diary is part of the larger diary held there, so is definitely Priscilla Wardle. After the war Priscilla Wardle married Cyril Terrence (Terry) Charles Kirby, an English soldier and they settled in Ballarat and later Melbourne. Terry Kirby became a Legatee in 1929 and transferred to Melbourne Legacy in 1935. He was a well liked, hard working Legatee and worked at Legacy House up to his death in 1967. That is probably how the diary ended up in the building. In May 2021 the pages were returned to descendants of Priscilla so now only electronic copies are in our archive.A valuable first hand account of life as a nurse in World War One.
