In November 2014 at the [[Adelaide Zoo]], an orphaned tree-kangaroo joey was transferred to the pouch of a yellow-footed rock-wallaby when his mother was killed by a falling branch. The joey survived, having been successfully reared by the surrogate mother rock-wallaby.<ref>{{cite web|url=http://www.abc.net.au/news/2015-06-30/adelaide-zoo-transfer-orphaned-joey-surrogate-wallaby-mother/6583042|title=Adelaide Zoo transfer orphaned joey surrogate wallaby mother|work=ABC News|date=30 June 2015}}</ref>
