The last main repatriation ship to leave Australia was the Orontes which left Melbourne 21st January 1947. The official records document that there were 779 Italian prisoners of war onboard: 19 officers and 760 ORs. German prisoners of war were also onboard to be disembarked at Cuxhaven.
The Italians arrived at Station Pier [Port of Melbourne] on six special trains which had come from Sydney, Adelaide and Victorian country centres.

A Perth newspaper published the above cartoon in Daily News on the 24th January 1947. In the bottom corner of the cartoon, you can see a man hiding with another man hiding in the trees at top right. The Australian military, in an effort to get escaped prisoners of war to surrender to authorities emphasised this was a last opportunity for a ‘free’ trip home to Italy. Additionally, if they surrendered, they would still be considered for migration to Australia at a later date.
The newspaper article on 24.1.47 explains that the majority of escaped Italian prisoners of war were in Western Australia. These men were given the opportunity to return to custody to board the Orontes.
