What's more, not even Australia's elected senators are permitted to know whether this is happening. It's assumed to be none of Australia's business whether there are foreign nuclear weapons in Australia.

This was clarified during a Senate estimates hearing on Wednesday, when Greens senators were condescendingly admonished by the Australian foreign minister for the very normal and appropriate attempt to clarify the government's policy regarding the presence of US armageddon weapons on Australian soil.

ABC News reports:

During a Senate estimates hearing on Wednesday Greens senators sought details on whether visiting American aircraft such as the B-52s operating out of the Top End are ever nuclear armed.

The committee was told the United States had a longstanding policy of "neither confirming or denying" the presence of nuclear weapons under its practice of maintaining global operational unpredictability. 

US bomber aircraft have been visiting Australia since the early 1980s, with nuclear-capable B-52s and B2 Sprits regularly operating out of northern Australia.
