Subsequently, he published several volumes of vindictive but amusing memoirs. He kept a diary throughout his career, but shortly after his retirement, the volumes of the diary were, he insisted, stolen from his home by ASIO agents. In 1985, he recorded 125 hours of an oral history interview with Adam Ashforth, for the Bicentennial History of Parliament's Oral History Project. Comprising more than a million words in transcripts, these interviews shine an extraordinary light on the history of organized labour and the Labor Party in Australia. Cameron was amazingly disciplined, diligent, and organized - one might say obsessive - in his record keeping. He kept notes, for example, on every round of caucus voting in every leadership election during his time in Parliament. He stored dozens of filing cabinets in his garage. The interview, according to the only person alive who has heard it, proceeds by Cameron recounting stories of his political life, interspersed with readings from the relevant documents (all of which are referenced, under questioning by Ashforth). Cameron was deeply suspicious of ASIO, probably for good reason. But his diaries were not stolen. In the 1985 interview he consults them constantly, taking them off the shelf in his living room. He also kept a set of copies in the safe of a Chinese gem dealer who lived in the neighborhood. These diaries and the interview will be an amazing source for historians of the Australian labour movement. Unfortunately, due to Australian libel laws, under which truth is no defence, Cameron chose to close access to the documents for 40 years - since even after his death, he knew, his estate could be sued for libel. And libel aplenty there is in these troves. His diaries, for example, document many instances where Whitlam induced his cabinet secretary to alter the decision of Cabinet. He is merciless, and fastidious to a fault, in his documentation of Whitlam's perfidy in giving Indonesia the green light to invade East Timor.
