The original ship was built in Glasgow in 1899 by Fairfield Shipbuilding and Engineering Co for the Orient Line. It was the largest Orient Line passenger ship completed in the nineteenth century and was the third vessel of the Line to bear the famous “O” prefix, which was traditional through to the last ship, the mighty 'Oriana'. Her dimensions were 8,130 gross tons, length 490.6ft x beam 56.6ft (149.50 x 17.22m). She had one funnel, two masts, twin screw and a speed of 18½ knots. Her maiden voyage from London, via Suez, to Melbourne and Sydney commenced on 3rd February 1899. She was the largest British flag ship sailing to Australia at the time and continued to regularly sail between London, Melbourne and Sydney throughout her life. She last sailed as a passenger ship between Melbourne and Sydney on the 3rd November 1916. During World War I, she was converted to a troopship and was used to transport soldiers and assist with military operations. She was torpedoed and sunk by German submarine UB-52, 40 nautical miles (74km) off the coast of Sardinia in the 12 May 1918. She was on her return journey from Alexandria to Marseilles with six other transports, carrying troops of the 52nd and 74th divisions when she was lost, resulting in one casualty. Her maiden voyage brought her to Melbourne in 1899. The ship carried the first Australian troops from Brisbane to WWI in September 1914.A large ship builder's model of the 'SS Omrah' an Orient Line one funnel passenger steamer of 1899.

This card relates to an excursion aboard “The SS Otway leaving the Warrnambool Jetty at 8 am April 18th 1873 to go to Belfast and Portland courtesy of the Warrnambool Steam Navigation Company Limited which was originally called the Warrnambool Steam Packet Company. The Otway was the second steamer purchased by the company. It had a number of ships which traded along the coast including, the Nelson, Julia Percy, Otway and The Edina. The Edina was originally owned by Stephen Henty who was operating it from Portland but he sold it to the new company for £8500. Henty then withdrew from the Belfast and Warrnambool trade for a time but it proved to be a competitive business. The name was changed again in 1878 to The Western Steam Navigation Company and the SS Otway was put up for sale. This card relates to one of the first trips, if not the first trip, taken by the SS Otway Shipping was a major part of the history of Warrnambool and this ticket is a link to one of the earliest passenger and freight services which operated along the coast.Small cream card with light purple text with company name at the top.

The forty-two navigational flags appear to be a complete set. Their purpose-built, grey painted wooden locker is divided into forty-two pigeonholes, each holding one of the rolled up flags. It is simply built and stands on short legs and was originally open-fronted, but has since been covered with a protective clear Perspex panel. The set of alphabetic and numeric visual signalling flags (including substitute and answering pennants) are made of wool in various colour combination designs, with canvas sewn to one end that is threaded with hemp rope. Some of the flags have metal clips attached to the rope. The flags were used for communicating messages to passing ships. Knowledge of visual signalling was mandatory for all lightkeepers and all stations maintained a set of flags. Although used for centuries, visual flag signalling formally developed in the nineteenth century and was published internationally as a system in 1857. By the early twentieth century it had developed into an effective means of conveying all kinds of short range visual messages. Most flags are in good condition and their first level significance is enhanced by their completeness and integrity as a set still housed in their original locker, and by the signal charts that remain in the museum collection which offer further insights into visual signalling.1 - 42.

An aeronautical chart is a map designed to assist in navigation of aircraft. Using these charts and other tools, pilots are able to determine their position, safe altitude, best route to a destination, navigation aids along the way, alternative landing areas in case of an in-flight emergency, and other useful information such as radio frequencies and airspace boundaries. World aeronautical charts have a scale of 1:1,000,000 and cover relatively large areas. Orbost Aero Club began in 1969 with Basil Dowie as Chair, David Nixon as Secretary/Treasurer. The group went into recess from 1977-1991 closing in 1997. The mid 1960s were boom years in flying training in Australia and the number of Aero Clubs grew rapidly. The Club played a significant role in the establishment of the small airport at Marlo and in the ongoing operation and development of the airport over the years particularly for patient transfer by aerial ambulance.

A prismatic compass is a common navigation and surveying instrument which was used extensively by the Forests Commission The compass most commonly used to run a traverse line. The compass calculates bearings of lines with respect to magnetic needle. A magnetic deviation correction was needed to convert the reading to a true bearing The compass could also determine angles between the traverse and waypoints (such as hilltop features). Commonly used for navigation. Largely replaced by modern GPS technology.Ex Army WW2 prismatic compass with leather case and strap. Rugged design and made of metal the internal compass plate floats on oil to help it stabilise The user lines up the direction of travel with the hair sightline in the fliptop cover and readings are taken through the viewfinder prism (hence the name).forest measurement, surveying, forests commission victoria (fcv)

Bubble Sextant model Mark 1XA type A.M. 6B/218 in protective storage box. Complete, with operation instructions. This is an aviation navigation instrument used by the RAF and RAAF during the World War 2 era. A sextant is used to measure the altitude of celestial bodies above a horizontal line of reference. A navigator can use the horizon as this line of reference, but when an aircraft is above the clouds or flying at night, the navigator can’t see the horizon. The bubble sextant solves this problem by providing an artificial horizon.The storage case has a label with the following: "A.M. 6B/218 MK IX A" and the number "10772/42 (V)"

An Octant is a doubly reflecting navigation instrument used primarily by sailors to measure the angular distance between two visible objects and was a forerunner of the sextant. The name comes from the Latin octo, or “one-eighth of a circle,” for the Octant’s arc which spans 45°, or one-eighth of a circle. The primary use of an Octant is to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation. The estimation of this angle is known as sighting or shooting the object, or taking a sight. The angle, and the time when it was measured, can be used to calculate a position line on a nautical chart (latitude), for example, sighting the Sun at noon or Polaris at night (in the Northern Hemisphere) gives an angle by which the latitude can then be estimated. Sighting the height of a landmark on land can also give a measure of distance. History: The principle of the Octant as an instrument to measure ones latitude was first implemented around 1742-present but was superseded by the improvement of the octant to a sextant, a very similar instrument, better made and able to measure bigger angles 120°, allowing the measurement of Luna distances to give longitude when used with an accurate chronometer. The sextant started to appear around 1730 and had been attributed to by John Hadley (1682–1744) and Thomas Godfrey (1704–1749), but reference to the sextant was also found later in the unpublished writings of Isaac Newton (1643–1727). Earlier links can be found to Bartholomew Gosnold (1571–1607) indicating that the use of a Sextant for nautical navigation predates Hadley's implementation. In 1922, the sextant was modified for aeronautical navigation by Portuguese navigator and naval officer Gago Coutinho. Henry Hemsley was a lesser-known instrument maker and optician working in London in the late 17th and early 18th century. However, it should be noted that there were two Henry Hemsley opticians and instrument makers around this period. (Henry Hemsley 1, 1786-89, who had premises at 85 Fleet St London and Henry Hemsley 2, 1828-56), whose workshop was at 135-138 Radcliff Highway London. Therefore, based on the inscribed workshop address Henry Hemsley 2 is responsible for making this example.The octant is representative of its type and although not fully complete it demonstrates how 18th and 19th-century mariners determined their latitude on a chart to navigate their way across the world's oceans in the 18th and 19th century. It also demonstrates the skill and workmanship of the early instrument makers that operated from London at this time and provided most of the navigational instrumentation use by commercial and military navies of the time.Octant, ebony wooden frame and handle.
