Three federal Labor MPs and two Labor senators have joined calls for large chunks of their own government's migration bill to be scrapped.
They say the bill, which would broaden the immigration minister's powers to force deportations, limits "numerous" human rights.
The comments were made by the parliament's human rights committee, which is tasked with scrutinising all bills to assess compatibility with Australia's human rights obligations.
Labor has the casting vote on the committee and five of its 10 members: committee chair Josh Burns, Alicia Payne, Graham Perrett and senators Karen Grogan and Jana Stewart.
