Fijian Prime Minister Sitiveni Rabuka will outline his nation's role in the Indo-Pacific during a visit to Australia, amid soaring regional tensions.

Anthony Albanese will meet with his Fijian counterpart in Canberra on Wednesday, where they will update the Fiji-Australia Vuvale Partnership, which sets out shared priorities of the relationship in a bid to strengthen peace in the Pacific.

The two nations will reaffirm they are committed to "ambitious" action on climate change, and continue to recognise it as the biggest threat to livelihoods and regional security.

They will also discuss bolstering disaster resilience.

Mr Albanese said he was delighted to welcome Mr Rabuka.

"Australia and Fiji are natural partners and we deeply value our close and longstanding relationship," he said.

"I look forward to strengthening our partnership with Fiji on economic recovery, promoting people-to-people links, security and cyber cooperation."

The leaders last met in Nadi in March, where they held talks at a peacekeeping and disaster relief camp.

Mr Rabuka will address a Lowy Institute event in Canberra on Tuesday, discussing increasing competition in the region as well as his developmental and economic ambitions for his country.

He will be introduced by Foreign Minister Penny Wong.

It will be the first visit to Australia by a Fijian prime minister since 2019.
