He just continued Gortons policy and the job was finished by Whitlam
Whitlam had nothing to do with the draw down, the only people left in country when he came to power were a few people tying up loose ends, a few members of the training team and the embassy guard. All Whitlam did was cancel conscription, which was no longer needed with our getting out. The draw down started before it was publicly announced, my unit was ordered to cease combat operations at 0530 local 9th June 1971, note the date on the Cabinet paper.
