The T&G Mutual Life Assurance Society was notable amongst Australian insurance companies for expanding its reach and visibility with a building program of 20 almost matching landmark buildings in cities and town across Australia and New Zealand in the interwar period. Other insurance companies also built numerous office buildings in many cities, but fewer in number or not all in matching style. Colonial Mutual built about eight matching office blocks across Australasia and South Africa (designed by Hennessy & Hennessy), while AMP built far more, but in various styles over many decades.
