Hugh Jackman and wife Deborra-Lee Furness have been given a pat on the back by Australian Prime Minister Tony Abbott for their work on overseas adoption.

The pair attended a function in Sydney on Thursday where Mr Abbott announced measures by the government to make overseas adoption easier.

Jackman and Furness, who have two adopted children together, were invited to Kirribilli House as part of National Adoption awareness week, which Furness is a founding member and patron.

Ms Furness has led an international campaign to make international adoptions easier.

She told the function orphaned and vulnerable children deserved to have a family.

"We're going to continue to highlight all the issues around adoption awareness," she told the function.

"We have to look after these kids."

Mr Abbott said he would reform the Australian adoption system, and discuss with the states ways to streamline the process of adopting children from overseas.

"To be born in Australia is to win the lottery of life and we would like to see more people winning the lottery of life by becoming Australians," he said.

He also took to Twitter later to thank the celebrity pair.

"Thanks to @Deborra_lee @RealHughJackman and @Lisa_Wilkinson for helping make adoption easier for Australian families," he tweeted.
