As Frank mentions in this interview that both he and Joan competed together at hill climbs in the early years and he would compete on the track. I remember meeting Joan Matich at Amaroo Park in Sept. 1970 and she was very friendly and nice and Frank was in a good mood as he had just enjoyed driving his new McLaren M10B Repco F 5000 car.
Here is an early photo of Joan and Frank from David Finch's collection.
