In a major speech at the Townsville army barracks, the Prime Minister is expected to commit to putting the Pacific back at the centre of our foreign policy, saying he wants to see a "southwest Pacific that is secure strategically, stable economically, and sovereign politically".
A $2 billion Pacific infrastructure fund is Scott Morrison's centrepiece of a new push to make the island nations the main priority of Australia's foreign policy.
Mr Morrison is also expected to announce a new defence force mobile training team, annual meetings of defence, police, and border security chiefs, and new diplomatic posts in a number of Pacific countries.
Amid concerns China is courting Pacific nations with infrastructure and loans, Mr Morrison will unveil a $2 billion Australian Infrastructure Financing Facility for the Pacific to support essential development and "stretch our aid dollars further".
The Coalition has previously been accused of failing to take the region seriously after Mr Morrison downgraded the Pacific portfolio in his ministry and skipped the Pacific Islands Forum in Nauru.
To complement the new fund, the Government plans to give Australia's export financing agency access to an extra $1 billion to invest in projects "which has a broad national benefit for Australia".
Mr Morrison will announce new diplomatic missions in Palau, the Marshall Islands, French Polynesia, Niue and the Cook Islands.
Ahead of next week's Asia-Pacific Economic Co-operation and East Asia summits, the Government has approached TV broadcasters about getting more lifestyle, news, current affair, drama and children's programs to the Pacific community.
A new sports pathway program will also provide stronger sporting links between the Pacific, which has a population of more than 11 million, majority in Papua New Guinea.
In a speech to be delivered today, Mr Morrison will declare it is time to "open a new chapter in relations with our Pacific family".
The move comes as Australia and China vie for influence in the Pacific.
Australia's Foreign Minister Marise Payne is scheduled to meet her Chinese counterpart in Beijing today, the first visit by a senior Canberra in two years after bilateral relations soured.
Australia has already this year pledged to develop several infrastructure projects in the Pacific but it has been forced to raid its aid budget to fund the projects.
Earlier this month, Australia said it would help PNG develop a naval base, beating out China as a possible partner for the port development.
