With Scott Morrison returning from a trip to the Pacific, both he and Bill Shorten will be on home soil over the weekend but not in their home towns.
The prime minister is set to spend Saturday and Sunday in Melbourne, while the opposition leader continues his tour of Queensland.
Neither has laid bare his exact plans but Mr Morrison will be involved in events across the weekend.
Mr Shorten on the Sunshine Coast on Sunday, is in the midst of a nine-day trip across Queensland in which he plans to hit 16 electorates.
Climate change was front and centre of Mr Morrison's trip to Vanuatu and Fiji this week, thanks partly to Fijian Prime Minister Frank Bainimarama's speech on Thursday urging Australia to move to clean power sources.
"From where we are sitting, we cannot imagine how the interests of any single industry can be placed above the welfare of Pacific peoples and vulnerable people in the world over," he said.
Mr Morrison is sticking with Australia's climate change targets despite the strong criticism, saying money will be spent to help Pacific nations tackle the effects of climate change.
The murder of an international student in Melbourne has also been front of mind for both Mr Morrison and Mr Shorten in recent days.
The body of Aiia Maasarwe was found not far from where she hopped off a tram in north-suburban Bundoora late on Tuesday night.
The prime minister said his heart went out to the 21-year-old's family, though he could not begin to think what he would say to them.
"I know what I'm thinking about her attacker. I expect it's the same thing that all other Australians are thinking today," he told reporters in Fiji on Friday.
"I know the police will do their job and they'll deal with it but the rest of Australia has to wake up today and deal with the most despicable of crimes.
Mr Shorten said the murder doesn't reflect the Australia or Melbourne he grew up in.
He said his feelings for the grief of Ms Maasarwe's family were strong but he wanted to reassure them Australia's police are among the best in the world.
"They will successfully catch, and our legal system will punish, the wrongdoer," he told reporters in Brisbane.
