be directly involved in politics". In March 1943, the head of the Commonwealth Security Service (CSS), Brigadier William Simpson requested a report into whether the newly formed IPA had sympathies with "fascism", "counter-revolution" or the powers that Australia was at war with, but his deputy director said that its committee and sponsors were "beyond reproach". The CSS was restructured in late 1943 and it again investigated the IPA's state branches. The IPA Queensland's radio play The Harris Family was required to be submitted to and approved by the Chief-Inspector (Wireless). The second review was completed in 1944. The CSS reported that nothing could be found to suggest that the IPA was subversive, and the war record of its supporters was "very fine", although two of the IPA NSW's council members were members of the Japan-Australia Society and one was associated with the Old Guard. The National Archives of Australia preserve the CSS' reports into each branch, as well as material collected in the course of their investigation. In October 1944, the IPA printed 50,000 copies of Looking Forward, an 80-page booklet which set out the possibilities of post-war reconstruction. Robert Menzies described Looking Forward as "the finest statement of basic political and academic problems made in Australia for many years". The IPA had no formal association with the formation of the Liberal Party of Australia by Menzies in 1945. Political scientist Marian Simms says that the IPA's role was to act as "an interim finance collector for non-Labor political interests", initiate "the unification of the non-Labor organizations in Victoria … and then [mediate] among them" and provide "much of the content of the federal platform of the LPA and propaganda for political campaigns". Looking Forward was influential in the Liberal Party's inaugural platform. Norman Abjorensen credits the IPA in this period with the collapse in ALP support, saying that the IPA was "the architect of a stream of propaganda that sought, successfully, to discredit Australia's very moderate Labor Party as a socialist tiger waiting to pounce once the war had ended." Keynesian consensus (1949–1972) During the 1950s and 1960s, the IPA "came to wholeheartedly support" Keynesian economics, with director C. D. Kemp writing "we are all socialists now". Over this period, the Institute argued for Australia's migration rate to be halved, which drew criticism from the Australian Industries Development Association and The Age. The institute also identified inflation as a
