He contributed drawings to The Bulletin, Worker, Sunday Times, Referee, and London Punch, but later became interested in aviation and radio, and did some remarkable work in connection with them.

Taylor was a member of the Dawn and Dusk Club, an association of bohemians and intellectuals that included the writer Henry Lawson.

On 5 December, at Narrabeen, Sydney, Taylor flew in the glider he had designed and became the first person in Australia to fly in a heavier-than-air craft.

At a conference of wireless experts called together by the Commonwealth government in May 1923 Taylor was elected chairman, and did valuable work in framing broadcasting regulations for Australia.

An epileptic, he died as the result of a seizure in his bathtub on 20 January 1928 leaving his wife, Florence Mary Taylor; they had no children.

The 25 January 1928 issue of the Construction and Local Government Journal contains an article 'The Life and Work of G. A. Taylor', which details the achievements and nature of this remarkable man.
