I'm pretty sure that the helmets don't have to be full face - just so long as they are standards approved. From the 2001-2002 ANDRA rule book (I don't have the latest with me) AS(Australian Standard) 1698 197/1988 SNELL (US) SA85, SA90, SA95, SFI31.2, M85, M90, M95, SFI41.2, 1985/1990/1995, SFI31.1 BS (British Standard) 6685-85 Type A, 2495, 1977 Most motorcyle retailers have good ranges of helmets. Places like Motorcycle Accesories Supermarket (MCAS) or if you are in the Campbelltown area go see Joe at Campbelltown Motorcycles in Blaxland road (Gratuitous plug for one of my dragsters sponsors )
