The parliamentary week in Canberra will start to the sound of cannon fire as Fijian Prime Minister Frank Bainimarama is greeted with a ceremonial welcome on his official visit to Australia.
Fiery exchanges can be expected to continue on Monday over embattled Liberal MP Gladys Liu when politicians go head to head in parliamentary question time.
Ms Liu, the member for the Victorian seat of Chisholm, is under fire over donations to the Liberal Party, which have been put at $1 million, and possible previous links to the Chinese Communist Party.
"This week we want two people to be accountable," Opposition Leader Anthony Albanese told reporters in Sydney on Sunday.
"The member for Chisholm should give a statement to the parliament."
He is also outraged that this scrutiny of a member of parliament has been described as racism.
"The only person who has said that this is about race is the prime minister ... (Scott Morrison) needs to stop this sort of behaviour," the Labor leader said.
He said Australia's had national security issues that needed to be debated soberly and maturely.
Otherwise, legislation is expected to be debated in the lower house on superannuation, military compensation, ABC funding, live animal exports and welfare.
The Senate will put the spotlight on laws relating to child sexual exploitation, veterans, aged care, bank reform and higher education.
First speeches are due from three new senators - Liberal Alex Antic, Nationals Perin Davey and Country Liberal Sam McMahon.
The prime minister will be jetting off to the US later in the week to attend a state dinner at the White House with President Donald Trump, the first such invitation since John Howard was hosted by George W Bush in 2006.
