Solomon Islands Prime Minister Manasseh Sogavare has offered assurances any constitutional changes to extend his time in office would be a one-time move, says Australia's Pacific minister.
Mr Sogavare wants to prolong his term in government until after the Pacific Games in November 2023.
The island nation's opposition has branded the move a power grab, saying elections would be able to take place alongside preparations for the Games.
Pacific Minister Pat Conroy says he has been assured by Mr Sogavare the passing of the bill would be a one-off and the four-year election cycle would return to normal following the Games.
Mr Conroy told ABC radio on Wednesday he welcomed the assurance and language of the bill.
"We believe that having regular election cycles is a key aspect of democratic norms and values which we share across the region," he said.
However Mr Conroy said it was a decision of the Solomon Islands parliament and people of the Solomon Islands, which Australia would respect.
He also flagged additional support for the island's election.
"Historically we have provided funding for elections and if asked, we would consider such requests," he said.
"Again, ultimately, this is a matter to be resolved by the democratically elected parliament of the Solomon Islands."
The comments come as Australia continues to leverage its diplomacy in the Pacific to ward off any Chinese military presence in the Solomon Islands following strengthening ties between Beijing and Honiara.
Taking assurances by both China and the Solomon Islands of no foreign military bases at face value, acting Prime Minister Richard Marles said Australia would be able to maintain its position as Honiara's security partner of choice.
"We want to build our relationship with Solomon Islands. It's a fundamentally important country for Australia," he told AAP.
Mr Marles, who is also defence minister, said any Chinese military presence in the Pacific would drastically change Australia's national security dynamic.
"But we fundamentally believe that by putting in the effort, by building our relationship with Solomon Islands, by thinking about the issues of their own development, we can be and continue to be the natural partner of choice," he said.
Former Pacific Minister Zed Seselja, who was sent to Honiara at the height of the federal election campaign, said the signing of the security pact "wasn't an act that was responsive to just how much Australia ... has supported the Solomon Islands".
Mr Seselja also provided a more frank assessment on whether Australia could trust Mr Sogavare's assurances.
"That remains to be seen," he told Sky News.
The former senator also flagged reviewing how Australia engaged with the region through aid.
"It's not about taking a punitive approach," he said.
"If the only message they get is you can get every increasing amounts of aid and support from the Australian government and you can do a deal with China ... then that's going to be a pretty concerning message as we look to other parts of the region as to what they'll take from that."
