After a slight delay, Australia and Papua New Guinea formally signed a defence treaty this week committing the two nations to come to each other’s aid if one is faced with an attack.
According to Prime Minister Anthony Albanese, the treaty also allows for up to 10,000 Papua New Guineans to join the Australian Defence Force (ADF). Some Australians may in turn join the PNG Defence Force.
This is a monumental change for the ADF and for its relationship with PNG. But it is far from an unprecedented one.
