Federal parliament sits for the final time with debate over anti-terrorism laws and energy policy setting the political scene ahead of an election year.
In the wake of recent terrorism events, Prime Minister Scott Morrison wants the parliament to urgently pass laws to help police and intelligence officers access encrypted communications in terrorism investigations.
As well, the government will seek Labor's support for laws to strip Australian citizenship from convicted terrorists.
Mr Morrison said he would not be bowing to critics who say the citizenship laws could breach international obligations by leaving people stateless.
"I dealt with that when I was immigration minister and they said I couldn't turn back boats and they said that wasn't legal," Mr Morrison told Nine on Friday.
"What I do is press on and I just get it done."
The swearing in of independent MP Kerryn Phelps on Monday morning, having won Malcolm Turnbull's former seat of Wentworth, will make the job of passing laws harder for the government in a minority-held parliament.
Dr Phelps will pursue laws to set up a national integrity commission, which are set to be debated in the lower house on Monday.
Labor may seek to exploit the minority parliament to seek the referral of Home Affairs Minister Peter Dutton and Liberal colleague Chris Crewther to the High Court over eligibility issues.
If Labor is able to add the six crossbench voters to its 69, referral motions could be successful.
Mr Dutton argues his family's interest in childcare centres does not represent a breach of the constitution.
Mr Crewther insists he is in the clear, despite his investment in a pharmaceutical company which was associated with a university research grant.
"I think the parliament needs to see what we can do about that matter rather than the government running a protection racket for people with clouds over their constitutional eligibility," Mr Shorten said on Friday.
Energy policy is expected to feature in question time, with Labor outlining its support for the National Energy Guarantee, which the coalition formerly supported.
The government is negotiating with Labor on laws to prevent schools from discriminating against gay students, which will be the subject of an inquiry report due on Monday.
Expected to pass parliament are laws to reform the aged care system, powers to call out the defence forces during terrorism events, improvements to indigenous rights and a new entitlement to five days of unpaid family and domestic violence leave in a 12-month period.
A controversial $450 million grant to the Great Barrier Reef Foundation will return to the spotlight when a report of an inquiry is delivered to the Senate.
Australians are expected to go to the polls in May.
