Three countries and three summits later, Prime Minister Malcolm Turnbull is heading back to Australia and into sitting week, where he says efforts will turn to the government's "national economic plan".
Mr Turnbull spent his final day in Pohnpei in the Federated States of Micronesia at a leaders retreat with other Pacific nations in which they discussed some of the region's main challenges - climate change, illegal fishing and disaster mitigations.
Mr Turnbull said he intended to continue coming to forums such as this and engage in the Pacific - something a number of forum nations have been quietly pushing for.
"In terms of the challenge of climate change we have a global problem, which is reducing greenhouse gas emissions that we all need to play a part in ... But then we also have the issue of adaptation and resilience and that is very specific from nation to nation," Mr Turnbull told reporters on Saturday.
"That is why we are working in a very granular and detailed way with the nations of the Pacific to ensure they are best able to proof themselves and be resilient in the face of climate change."
His visit to Pohnpei wraps up a week of talks with world leaders in which various topics dominated the agenda.
At Hangzhou Mr Turnbull urged China, like other G20 countries, to roll out more reform to open access to markets and opportunities for investment.
Meanwhile, at the Laos capital Vientiane counter-terrorism and the ongoing tensions around territorial disputes in the South China Sea were never far from leaders' lips.
Mr Turnbull will head back to Canberra on Saturday night and into a difficult parliament where he will no doubt face questioning over the year that was - with the anniversary of his toppling of Tony Abbott coming up this week.
"We have a very big program ... The critical issue for us now is to ensure that we continue to deliver on our national economic plan.
"It's been a year of considerable progress and considerable achievement."
"Our economic performance is the envy of most of those countries around the G20 table. There are very few developed nations that have economic performance as strong as Australia's."
