After making significant inroads with world leaders in Washington, Beijing and the Cook Islands, it will be back to the grind of domestic politics for Prime Minister Anthony Albanese.

Both houses of parliament will sit from Monday, following a week of Senate-only business.

The return of parliament comes after the PM solidified the US-Australia alliance in Washington last month with President Joe Biden, before last week becoming the first Australian leader to visit China in seven years and defrosting the relationship with President Xi Jinping.

Mr Albanese also unveiled a new partnership with Tuvalu while at the Pacific Islands Forum.

He returns to debate raging on contentious workplace reforms, which will add protection for gig economy workers and allow casuals to transition to permanent work.

The Senate last week voted to remove non-contentious elements from the bill, such as greater protection for emergency workers and those facing domestic violence, to have them in operation by the new year.

The lower house will come under pressure to vote for the carved out bill, as debate continues on the broader measures.

Gambling reforms, a strengthening of disability support and further tranches of paid parental leave will be the focus of the House of Representatives.

Measures making it easier for older Australians to re-enter the workforce are also be on the agenda.

In other matters, the house on Monday will mark the fifth anniversary of the apology to victims and survivors of institutional child sexual abuse.

While in the Senate, a political fight is brewing over controversial changes to the Murray-Darling Basin Plan, with debate set to take up a large portion of the week.

Senators will also focus on a contentious sea dumping bill, along with counter terrorism measures.

Events in the Middle East are expected to be the subject of much debate across the week, amid growing calls for a ceasefire in the region.

Political leaders have urged greater social cohesion following clashes between pro-Israel and pro-Palestinian groups at protests in Australia.
