"Every member will bring their own unique skills and expertise – including experience of advocacy in the welfare system, economics, health, business and research and analysis. It's also important to me that the group includes members with lived experience of the welfare system."
The overhaul of the welfare system is part of the Coalition Government's confidence and supply agreement with the Green Party.
Under-Secretary Jan Logie said the Greens welcomed the establishment of the group.
"This Government knows there are immediate changes we need to make to our welfare system, which we are working on. But we also need to take a long-term view and ensure the whole system is working effectively and compassionately."
The Public Service Association said frontline Work and Income staff should be asked for their perspectives in the review.
"They will have their own perspectives on where the stresses are in the system and how they can be remedied," PSA national secretary Glenn Barclay said.
"We are proposing mechanisms by which employees can feed their knowledge and concerns to the Welfare Expert Advisory Group, not just in the form of submissions but throughout the process."
The expert group will report back to the Government with its recommendations in February 2019.
