A 75-Year History

Headquartered in Melbourne, A.G. Coombs was established by Allan George Coombs in August 1945 at the end of the Second World War. A plumber by trade, Allan possessed nothing but a pushbike, a kit of tools and a bucket-load of determination when he started his business.

Assisted by a small loan, Allan purchased an Austin utility truck, appointed his first apprentice and built a garage and workshop in the backyard of his brother’s home.
