3 June – A skit involving terminally ill children and the fictional 'Make a Realistic Wish Foundation' (a parody of the Make-a-Wish Foundation) causes public outrage after airing on an episode of The Chaser's War on Everything on ABC1. The skit involved The Chaser members Chris Taylor (as the foundation spokesperson) and Andrew Hansen (as a doctor). The premise of the skit was that if the terminally ill children are only going to live for a few more months before dying, it is not worth spending money on lavish gifts for them. It portrayed the children requesting extravagant items such as a trip to Disneyland and the chance to meet Zac Efron, with Taylor and Hansen instead giving them a pencil case and a stick respectively. The skit concluded with Taylor stating "Why go to any trouble, when they're only gonna die anyway". Following public criticism of the skit, both The Chaser and the Australian Broadcasting Corporation issued statements of apology. The ABC subsequently suspended the series for two weeks following the controversy. The series returned on 24 June.
