The only IUD of Australian origin, developed in 1971 by Australian doctor Ian Anderson in partnership with Ansell Australia and produced at the Ansell factory, 18 River Street, Richmond in the 1970s. The device was taken up by the Battelle Foundation, USA, and clinical trials were carried out in Israel, Indonesia and Singapore. No formal clinical trials were carried out in Australia. The device was used extensively by Population Services International, a private abortion clinic in Sydney in the mid 1970s. At the time this device was donated to the collection in 1997, there were legal proceedings regarding two Australian women who claimed ongoing problems as a result of its use. The donor, Dr Richard Gutch, practised in Clifton Hill and used some in the 1970s but not for long. The drawbacks were the multi-filament string acted as a wick for infection, also the latex leaf often came away from the thread when pulled for removal. Curettage was often the only effective way to remove the IUD. Dr Gutch removed many as he developed a reputation for being skilled at their removal.Intrauterine device (IUD), Ansell-Anderson latex leaf design, with paper sleeve.

Trial Bay opened in 1886 after 13 years construction. It was designed for prisoners who were low risk and nearing the end of their sentences. From here they would participate in Public Works projects. It was named Trial Bay after the brig "Trial" sank there. This ship had been commandeered by convicts in Port Jackson and forced to sail north. Between 1915 and 1918 the prison became a detention centre for German citizens.Trial Bay Gaol, Public Works Prison and Wartime Detention Camp, a Macleay River Historical Society publication Kempsey, New South Wales, small booklet with black and white photographs.Marie h Neilhistory, australian, prisons, australia-history-nsw-prisons
