The class action is seeking compensation for the forced removal of Indigenous Australians from their families in the Northern Territory between 1910 and the 1970s.

At the case's first management hearing in Sydney on Thursday, the NSW Supreme Court was told the Commonwealth has posed a series of questions to the lead plaintiff Eileen Cummings since the claim was filed in April.

The government would also in coming weeks formally seek more information on the particulars of the plaintiff's statement of claim, the court was told.

The plaintiff, who is chairperson of the Stolen Generations NT organisation, is to serve replies to those information requests by July 26, Justice Robert Beech-Jones ordered.

The Commonwealth must file and serve its defence by October 1, ahead of a case management hearing on November 19.

Justice Beech-Jones was told the case was filed in Sydney as the NT lacks a class action regime.

In April, Shine Lawyers' Tristan Gaven said most states had taken steps to compensate stolen generation survivors but no such action had occurred in NT.

One member of the class action, 84-year-old Heather Alley, was nine years old when forcibly removed from her mother and transported from Mataranka, south of Katherine, to western Sydney.

She later lived in an Alice Springs hostel, where she was flogged, she says.
