Reaffirming ties with fellow leaders on the world stage could provide a circuit breaker for Anthony Albanese amid domestic and economic woes.

But a likely interest rate hike triggered by higher-than expected inflation levels while the prime minister is overseas will make his job, and that of his treasurer, even more difficult.

The prime minister will fly out on Saturday for the Caribbean where he will attend the Commonwealth Heads of Government Meeting in Antigua and Barbuda.

Mr Albanese hold talks with King Charles and allies such as UK Prime Minister Andy Burnham and Canadian Prime Minister Mark Carney at the biennial meeting with Commonwealth leaders.

The meetings would be a well-needed reset for the government, after controversies over grant funding and pressures on inflation, Monash University associate professor of politics Zareh Ghazarian said.

“It is a strategically important time for him. He’s got a lot of spot fires burning domestically, but this is going to be an opportunity for him to present himself to be much more on the front foot,” Dr Ghazarian told AAP.

“There’s a lot of pressure, so this trip could just be a moment to reset the political debate for people.”

The meeting with Commonwealth leaders will kick off a busy end to the year overseas for the prime minister, with international summits in Turkey, the Philippines, China and the US in coming weeks.

International pressures following the war in Iran and trade issues had made those bilateral meetings with world leaders even more important, Dr Ghazarian said.

“The big thing at the moment for the government essentially is this idea of trade, and for Anthony Albanese, this is a critical moment to present himself as a world leader amongst other world leaders,” he said.

“He’s essentially got to put out all the stops to make this trip matter and matter in important ways.

“It’s going to be an important opportunity for him to demonstrate how he’s going to handle this really delicate and very tricky economic situation he has domestically by plugging into the broader international community.”

The prime minister will be away when the Reserve Bank hands down its next interest rate decision on Tuesday, with markets tipping a rise to 4.85 per cent.

It would be the fifth interest rate hike in 2026, a situation that would be challenging for Treasurer Jim Chalmers to handle, Dr Ghazarian said.

“When the prime minister is overseas, greater pressure is placed on those who remain representing the government,” he said.

“For Jim Chalmers, I would think that the next few weeks are going to be a real test of his political ability, his ability to communicate with the Australian community, and essentially explain the government’s position and plans for the medium term.”
