Australia does not permit foreign military bases on its soil, but hosts US Marines for exercises for six months of the year in the northern city of Darwin.
A rotating force of US-commanded submarines will arrive in Western Australia next year.
Pressed on what the expanding force posture would entail, Marles told journalists co-operation was also taking place in “logistics, co-operation, in respect of our air forces, cyber, and space”.
He said the expanding co-operation was a response to “the biggest conventional military build-up by any country in the world since the Second World War in the form of China”.
“We need to be ensuring that we build deterrence, that we build balance, so that we can provide for the peace and stability of the region in which we live,” he said.
“Collaboration through the alliance with the United States is fundamentally important to that.”
Among those areas of co-operation are US Marine Corps plans for a crisis-ready stockpile in Australia, AFP reported in June.
Australia has also embarked on its largest military spending project to build nuclear-powered submarines next decade under the Aukus agreement with the United States and Britain.
Critics have said the deal does not guarantee that Australia will receive the submarines.
