Beazley had appeared on Channel 9’s Sunday program responding to reports that US bases in Australia were intercepting telephone and other electronic information in friendly countries and within Australia. "We say emphatically that the facilities do not spy on Australia," Beazley said. Pine Gap's role was to help verify arms control agreements and provide adequate early warning of missile launches, he said.

The cable, written on April 1, 1985 from the US embassy in Canberra to the Secretary of State in Washington, gives the details of Beazley's TV appearance and Ball's comments.

It reports, without comment, that Beazley said the Australian government "is fully aware of everything that takes place at the joint facilities and that [government] approval is required for any specific activity". It also carries a handwritten addition by an unknown person, presumably at the US State Department, commenting on Ball's claims. A mysterious addendum to a US diplomatic cable from April 1, 1985, confirms the existence of a secret room at the Pine Gap spy base near Alice Springs - a room Australians are not permitted to enter.

Next to the description of the first room the handwritten addendum says "CORRECT, but Hayden, when Shadow PM, did enter area once".

Next to the description of the second room the handwriting says "NO SUCH AREA". Close up: the mysterious handwritten addendum to a US diplomatic cable Credit:Privacy International Ball had written in 1984 that Pine Gap was administered by the CIA and "originally established as part of Project Rhyolite", which involved a satellite "sucking up like a vacuum cleaner a wide spectrum of Soviet and Chinese military communications" including telephone calls as well as radar and other signals associated with missile launches. He said later he learned about the Rhyolite program in 1977 but "I was uncertain about whether the Rhyolite program was Pine Gap’s only function until Hayden confirmed it for me in April 1981, after he returned from a tour of the facility". It seems likely this is the visit referred to in the cable.

The cable came at the height of the "ban the bomb" campaign in Australia, a day after more than 300,000 people marched across Australia in Palm Sunday anti-nuclear rallies, and the People for Nuclear Disarmament had claimed their membership had grown by 100,000 on the previous year. Then foreign minister Bill Hayden was on the back foot, the Sydney Morning Herald reported on April 1, saying the marchers' concern about the arms race was entirely justified but Australia could not "pull up the drawbridge and tell the world to go away... the objective must be no less than the elimination of nuclear weapons and of war itself". On April 1, 1985, the Sydney Morning Herald reported Kim Beazley's claim the day before that the government knew everything that happened at the US Pine Gap spy base near Alice Springs. It also carried a report on a huge 'ban the bomb' march.

"Among the functions performed are the provision of early warning by receiving from space satellites information about missile launches, and the provision of information about the occurrence of nuclear explosions," he said.

In 2013, it was revealed that Pine Gap played a key role in the US' controversial drone strikes against al-Qaeda and Taliban leaders in Afghanistan and Pakistan, tracking the precise geolocation of radio signals including hand-held radios and mobile phones across the eastern hemisphere from the Middle East across Asia to China, North Korea and Russia. A defence white paper released in 2016 said Pine Gap delivered “information on intelligence priorities such as terrorism, the proliferation of weapons of mass destruction, and military and weapons developments, while contributing to the verification of arms control and disarmament agreements". Then Opposition Leader Bill Hayden, pictured with Bob Hawke, was the only Australian to enter a secret room at Pine Gap.

"Despite these dramatic changes, in many countries around the world, the public remains in the dark regarding state surveillance powers and capabilities."
