Australian Security Intelligence Organization [PDF ebook] 
An Unofficial History

This book traces the history of Australia’s highly secret Intelligence Security Organisation. Established in the early days of the Cold War, like most intelligence organisations working under covert conditions, it exceeded the vague powers entrusted to it. It has been the subject of two Royal Commissions in Australia and in recent times several acts of Parliament have been passed in order to make it more accountable to Australia’s government and its citizens.
