Australia's returned prime minister Scott Morrison is being urged to move boldly on climate change policies to improve relationships with Pacific neighbours.
But observers said no substantial change is expected for Australia's engagement in the region after the Coalition's surprise win at the weekend.
Shane McLeod of the Australian thinktank, the Lowy Institute, said Australia's so-called Pacific step up, a suite of policies and funding initiatives brought in in 2017, will likely continue.
But he said with losses on the hard right, there may be more room for the government to manoeuvre on climate change.
"The fact that some of those people have departed, for example the former prime minister Tony Abbott is no longer in parliament, may give him more space to move.
"It may give him space to come up with his own approach and to really take that on and not be beholden to some of the factions and some of the voices that have really held the government back over a long period of time."
Fiji PM urges 'underdog' ScoMo to fight climate change
Meanwhile, Fiji's prime minister Frank Bainimarama has congratulated Scott Morrison on his victory.
In a post on social media Mr Bainimarama said Mr Morrison's trip to Fiji earlier this year was the beginning of a new chapter in relations.
He said the "vuvale" reset aligned the countries' foreign policies to better reflect shared national interests and deep values that bond Fijians and Australians.
Mr Bainimarama said Fiji is looking to the months and years ahead with great hope and anticipation.
Wananavu, @ScottMorrisonMP! With you, the newfound closeness between Fiji and Australia feels not only genuine, but personal. Fiji is looking to the months and years ahead with both great hope and bated anticipation.

He urged Mr Morrison to take the same "underdog attitude" that inspired his parliamentary victory to the global fight against climate change.
Mr Bainimarama has criticised Australia's relative inaction over climate change and has been urging it to shift away from coal and mining.
