Labor leader Anthony Albanese says increasing foreign aid and addressing climate change are crucial to maintaining stability in the Pacific after Solomon Islands signed a security pact with China.
The deal has triggered geopolitical anxieties for Australia and the US, both wary of China's expansionist footprint in the Pacific.
Mr Albanese says if given the opportunity to lead a government he would maintain Australia's critical foreign aid to Pacific nations.
"We wouldn't have cut funding to aid," Mr Albanese told reporters in Sydney on Saturday.
"The other thing is creating stability in the region by acting on the most important issue for our Pacific neighbours, which is climate change," he said.
His comments come after the Pacific nation defended signing a security deal with China, leaked on social media, allowing its ships to be based in the Pacific and to have a navy base.
In a statement on Friday, the Solomon Islands said "broadening partnerships is needed to improve the quality of lives of our people and address soft and hard security threats facing the country.
It also flagged how the deal would translate positively on the ground with the inclusion of development funding.
"The proposed security arrangements have a development dimension to it, covering humanitarian needs of the country besides maintaining the rule of law," the statement read.

She also said that the Australian peacekeeping force in the country will be extended until December 2023, after a request from the Solomon Islands.
Ms Payne said other initiatives are also in the pipeline, including a radio network to integrate police, health and disaster management across the country; and a second patrol boat outpost on Solomon Islands’ eastern border.
"Australia will continue working with our Pacific family, consistent with our values and the Pacific way. Last year, Australia spent a record $1.7 billion in development assistance and will continue responding to our Pacific partners’ priorities such as climate change, COVID-19 recovery and economic and security challenges," she said.
A spokesperson for the US State Department said the draft security agreement and the police deal did not address the underlying issues that contributed to the unrest in November.
"We do not believe (People's Republic of China) security forces and their methods need to be exported," the spokesperson added.
"This would only fuel local, regional and international concerns over Beijing's unilateral expansion of its internal security apparatus to the Pacific."
Solomon Islands switched diplomatic ties from Taiwan to Beijing in 2019, which partly led to deadly riots in the capital Honiara in November last year.
Australia, which has historically provided security to the Solomons, led a policing mission after the riots, following a request from the country's prime minister, Manasseh Sogavare.
Last month, Washington said it would open an embassy in Honiara amid fears China was seeking to strengthen military relations there.
