The Wolverine star joined Deborra-lee Furness at the event in Melbourne, Australia in aid of Adopt Change, which campaigns to raise awareness of adoption issues and change legislation to ease the legal process for childless couples.

Furness took the opportunity to reveal the organisation is making huge progress since she helped launch it in 2008, telling the Herald Sun newspaper, "(Australian Prime Minister) Tony Abbott has stated that the wait time will change from seven years to an average of 12 months - that is huge. We are also working at establishing centres of excellence to support adoptive families and adoptive kids. But I think the biggest shift is that we have put this on the agenda, where for decades people wouldn't talk about it."

Jackman and his wife, who are based in the U.S., are parents to two adopted children.
