Australia and the US are in talks to deepen their military co-­operation, with plans for new ­exercises on Australian soil ­including joint training with American army soldiers.

The proposed exercises with the US army would be modelled on the annual rotation of Marines through Darwin, and use a variety of military training areas including those in Queensland.

The Morrison and Biden ­administrations are also in the midst of delicate negotiations to build guided missiles in Australia using top-secret US technology, and store US weapons and equipment at Top End bases.
