Clifford, the second son of John Joseph and Alice Regan, was born at Inverell in 1892. Known as Gus, he went to school in Inverell and like his elder brother was a keen sportsman. He was a strong swimmer and played Rugby Union at Inverell. After moving to Tamworth to begin his own business he continued to play Rugby Union there and served on the committee of the Half Holiday Sub Union.
Twenty two year old Clifford enlisted in April 1915 and sailed from Australia the following June with the 3rd Battalion. He served at Gallipoli where he became ill and was admitted to hospital at Mudros before being evacuated to England for treatment. Upon recovery he returned to duty and was appointed Warrant Officer at Forvant. During September 1918 Clifford was recommended for the Meritorious Service Medal which was awarded in 1919 after he had returned to Australia.
Once home and back in business in Tamworth, Clifford had his own Rugby team known as Regan’s. They did extremely well, beating the opposition business teams many times over.
Clifford (Gus) Regan died in June 1947 at Cowra.
