Hi, another build from me it’s the crusade to beat wiimini...

Wiki things:

Australia first showed an official interest in replacing its CAC Sabre with the Mirage III in 1960, and initially considered a variant powered by a licence-built variant of the Rolls-Royce Avon turbojet (used by the CAC Sabre). While an experimental Avon-powered Mirage III was built as a prototype and flown in trials, it did not result in use of the Avon by a production variant.

The Australian government decided that the Royal Australian Air Force (RAAF) would receive a variant based on the Mirage IIIE and powered by the SNECMA Atar engine, built under license by Government Aircraft Factories (GAF) at Fishermans Bend, Melbourne. Known as the Mirage IIIO or GAF Mirage, the Australian variant differed from the Mirage IIIE mainly in its avionics. The other major Australian aircraft manufacturer at the time, the Commonwealth Aircraft Corporation (CAC), also based in Melbourne, was also involved in the project, producing the Atar engine under licence.
