On 21 March 1927, Wackett was elected the inaugural chairman of the NSW Division of the Institution of Aeronautical Engineers (IoAE) in Sydney. The following year, after the amalgamation of the Royal Aeronautical Society (RAeS) and the IoAE parent body in Britain, he was appointed the inaugural deputy chairman of the Australasian Branch of the RAeS. He also found time to act as the New South Wales RAAF Aide de Camp to the Governor General, although the duties were not onerous.
