Sorry for the late reply and thanks for the question,

The Australian 2024 national defence strategy says this: "Our Alliance with the US remains fundamental to Australia's national security. We will continue to deepen and expand our defence engagement with the US, including by pursuing greater scientific, technological and industrial cooperation, as well as enhancing our cooperation under force posture initiatives"

US has these military facilities in Australia (and more secret ones):

"Australian Defence Satellite Communications Station – located near Kojarena 30 km east of Geraldton, Western Australia. Other U.S. bases in Australia are present and this list does not include ADF bases with U.S. access. The U.S. military has access to many ADF training areas, northern Australian RAAF airfields, port facilities in Darwin, Fremantle, Stirling naval base in Perth, and the airfield on the Cocos Islands in the Indian Ocean." Wikipedia

US also has a Rotational U.S. Army, Navy Presence where they bring their submarines and provide financial benefits to many military services they can use (RAAF bases and the assisting in manufacturing of missiles and other weapons). There are 2500 US marines on permanent rotation

According to US gov "The United States is Australia’s defense goods and services partner of choice" and "The U.S. has over $27 billion in active government-to-government sales cases with Australia" most of Australias military equipment comes from the US including their nuclear submarines

Also most aggregiously

"As documented by CIA whistleblower Christopher John Boyce and several authors, including John Pilger,[7][4][6] as well as some Australian politicians,[8] the CIA allegedly backed Governor-General and representative of Queen Elizabeth II in Australia, Kerr, to dismiss Whitlam, due to Whitlam's perceived left-wing policies[3] including Australian withdrawal from the Vietnam War, as well as his views on Australian sovereignty.[3] His conflict with the CIA is alleged[3] to have come to a head when he discovered several CIA-led operations occurring in Australia and overseas conducted by ASIO and ASIS, leading him to threaten cancellation of the lease on the Pine Gap facility, ending the US-led (nominally joint) operation, which was integral to the CIA's signals interception operations in the southern hemisphere"

"In a statement to parliament on 3 April 1974, Whitlam said: "The Australian government takes the attitude that there should not be foreign military bases, stations, installations in Australia."

He was then sacked and replaced by a more agreeing pm by the CIA Wikipedia

There are also numerous traid agreements that leads to Australia relying on US for a lot of its financial security (though it relies on China and Japan as well). And also many Australian companys are US owned/funded

This is all the research I have time to do but there are many, many more examples of American interference and control.

Edit: also America controls most of Australian media including News Corp Australia (owns most newspapers and News Corp is also the controlling shareholder of Foxtel and it owns Sky News in Australia. And much more)

also the American controlled ABC is the most visited site In Australia. And controls a lot of other media

What do you expect from a country that believes it can bomb others into “democracy”?

(Saying that as an American. Also, I’m sorry, please take in vermont as a territory we’d make a great addition to the maple syrup confederation)
