The leader of Papua New Guinea says Australia and his nation are like family, and like all families have their issues.
After meeting with Prime Minister Scott Morrison at Parliament House, in which they pledged annual leader-level talks, James Marape said "no relationship is more important" to PNG as its link with Australia.
It's a union which goes both ways, Mr Marape reminded the prime minister, as the Pacific nation could play a vital part in linking Australia to Asia.
"You can walk across to Asia from PNG - we are in a strategic hub," the PNG prime minister told a media conference in Canberra on Monday.
Mr Marape wants to leverage his nation's position to help its struggling economy for the "mutual benefit of countries in the region, including Australia."
The two nations shared economic, security and community relationships but Mr Marape said that "above all, it is a relationship of family."
Mr Marape is the first official foreign leader visit to Australia since the re-election of the Morrison government in May.
Following a private chat over tea, the pair fronted a joint press conference in Canberra in matching ties.
Mr Morrison invited Mr Marape as part of his "Pacific step-up" strategy, aimed at increasing Australia's economic and security engagement with its neighbours.
The leaders have agreed to hold an annual dialogue to improve ties, which have frayed in recent years as PNG turns increasingly to China for financial support.
Australia already gives PNG more than half a billion dollars in aid each year.
The prime minister announced a further $250 million in grants and loans to bring low-cost electricity to PNG's Ramu grid.
The funding, part of Australia's joint commitment with the US, New Zealand and Japan, will help developing PNG hit a target to connect 70 per cent of the country to electricity by 2030.
About $79 million will also be split between rural health, child immunisation and the fight against drug-resistant tuberculosis, while the issue of security will receive $135.9 million over three years for a long-term policing program.
Mr Marape - who is accompanied by wife Rachael and several ministers - spruiked his nation as a destination for Australian investment, which he said was currently worth about $17 billion to PNG.
He also met in private with Labor leader Anthony Albanese.
The visit comes days after Greens senator Nick McKim was kicked off Manus Island after trying to visit an asylum seeker facility.
Senator McKim denied doing anything wrong, and said he had followed procedures undertaken on past visits.
Thousands of people also attended rallies in Australia's major cities on Saturday calling for an end to offshore detention.
Friday marked six years since the Rudd Labor government reintroduced offshore detention for asylum seekers who arrived by boat.
