From theconversation.com: Australia’s Defence Minister Richard Marles has initiated negotiations for a defence treaty with Papua New Guinea, amidst concerns about China’s growing influence in the Pacific.

There are four questions to be addressed: the enforceability of the treaty, whether Australia can manage associated risks, the financial implications for Australian taxpayers, and the long-term defence strategy in PNG, especially regarding the potential establishment of military bases.

Historically, Australia has been cautious about committing to a binding security guarantee with PNG.
