The only other information I have on Colin is that on the list of soldiers returning to Australia aboard the HMAS Sydney, he was detailed as having his destination, 5 Fourth St, Lithgow.
I also note from the AWM website, he was born in Lithgow on 19 June 1948.
In Vietnam he served in 1st Australian Reinforcement Unit from 3 Sep 1969 to 23 Sep 1969 before joining D Company 5RAR on 24 September and remaining with us until we arrived in Sydney on 10 March 1970.
