There's an exploratory Government mission across the ditch to find out more about AUKUS.

Foreign Affairs Minister Winston Peters and Defence Minister Judith Collins have met with their Australian counterparts, Penny Wong and Richard Marles, in Melbourne.

"Pillar two is a sort of military, technology sharing agreement, which has been on the table for quite some time."
