Separately, Attorney General Christian Porter delivered the final report on the trial at the tribunal in late December by former High Court Judge Ian Kalinan.
It is expected that the audit will recommend to rationalize the Tribunal's bureaucracy, which rose from 530 in 2016 to 660 in the last financial year.
A spokesman for the Department of Public Prosecutor confirmed members whose conditions expired in May and June were asked to submit their documents at "early January".
"After all, the proposed candidates, the time and the number of appointments recommended to the governor are questions for the government," he said.
These members were designated by then-lawyer George Brandis in July 2015 and largely chaired the appeals for migration decisions.
The tribunal was set up in the same year after the merger of the former Socialist Appeals Court, the Migration Preview Tribunal and the Refugee Examination Tribunal.
While the decision to re-appoint members will be made after the verdict of summaries and private interest declarations, the early start of the process increased intrigue.
Some sources with experiences from the tribunal's meetings pointed out that the process usually lasts for two months, while Labor closely follows and is likely to object if the members are re-appointed close to the date of the election.
The last Ipsos survey conducted for Herald in December, shows that the government lags behind workers 46 percent to 54 percent.
Ministerial spokesman Greg Hunt, Acting Attorney General, while Mr. Porter is on leave, refused to comment on whether the government had requested the start of the re-appointment process or whether a decision would be made to reinstate members before May.
"The government will review and announce the announcement of the appointment of AAT at appropriate times, including any re-appointments for existing members whose terms should expire, this is part of the standard process that has been in place for many years," he said.
The tribunal is in the spotlight after several controversial decisions, including two US armed robbers, Teak Karan and Louis Burton, abolished visas last year despite a former prisoner in 2012 for a series of armed robberies, while the latter was found guilty of using a screwdriver to stab the victim in the chest.
In another matter, the Irish convicted pedophile priest Finian Egan received an appeal against deportation after he made the decision of Mr D. Daton to take away his double Australian citizenship.
However, figures published by the tribunal show very few of the decisions they have taken, only 3.1 per cent in the financial year ending June last year, appeals were filed to the courts.
The tribunal reviews appeals for decisions on the National Disability Insurance Scheme, veterans issues and those related to social security payments.
However, migration decisions remain the overwhelming majority of complaints, with 37,900 submitted last year, 17,900 finalized and another 44,400 open.
