Many of its staffers and supporters have been prominent in Liberal Party affairs and some in governments. The most obvious was the Liberal Party's most famous 'Dry' MP, the Libertarian Federal government minister [[John Hyde]] who ran the Western Australian-based [[Australian Institute for Public Policy]] (AIPP). In 1988, the sons of CD Kemp (who had inherited control of the IPA from their father), Charles Roderick (known as "Rod") Kemp and his younger brother David Kemp both won preselection for Liberal Federal parliamentary places in Victoria. The lawyer Rod Kemp became a Senator, and David (academic political scientist and advisor to PM Malcolm Fraser) won a safe seat in the House of Representatives.
John Hyde, who had retired from government was brought in to take control of the IPA and merge his AIPP into the organisation. He brought into the IPA his WA staff of [[J Ray Johnstone]], Chris Uylatt and [[Mike Nahan]]. Another Executive Director [[John Roskam]] ran for Liberal Party preselection for a number of elections: and at a later stage the then CEO [[Mike Nahan]] became Treasurer and leader of the Opposition in Western Australia.
In 19871988, [[Gerard Henderson]], who had been running the South Australian branch of the IPA was exposed for promoting the tobacco industry funding of the Adelaide Formula One Grand Prix, .<ref>Henderson's wowser claims - [https://www.industrydocuments.ucsf.edu/docs/xgnh0030]</ref> and its "tobacco sponsorship Bill". He was shifted quickly relocated to Sydney where it his operations came into competition with Greg Lindsay's Centre for International Studies (CIS) which . The CIS was a long-established primary part of the US Libertarian "Atlas Group" network, and it received substantial funding from Philip Morriswith links to think-tanks across the Pacific.
The IPA, based in Melbourne had established its Libertarian network links along with the Perth AIPP, and South Australian and Singapore IPA subsidiaries with to the London [[Institute of Economic Affairs ]] (IEA) in London, and therefore with the [[Mont Pelerin Society]]. It serviced British-American Tobacco (BAT) (WD&HO Wills in Australia) and looked to Europe for much of its funding. John Hyde and Greg Lindsay met in late 1988 and struck a territorial agreement in 1988, which forced Gerard Henderson to leave the IPA and set up his own [[Sydney Institute ]] think-tank, which continued to be funded by Philip Morris.
Following the 2007 federal election defeat of the Liberal Party, ''[[The Australian]]'s'' journalist Christian Kerr noted that a new group of federal Liberal politicians were "receiving support from former Howard government staffer John Roskam" at the IPA.<ref>Christian Kerr, [http://www.theaustralian.news.com.au/story/0,25197,24700742-5013871,00.html "Liberals' growing hunger"], ''The Australian'', November 25, 2008.</ref>
