Speedcafe.com understands that further work, dubbed by some as a ‘mini VCAT', is set to take place next week.
The location is thought to be Temora Aerodrome, where a booking of several days is believed to have been made.
Notably, the homologation teams, Triple Eight Race Engineering for Chevrolet and Dick Johnson Racing for Ford, are both supposed to be testing their race cars next week at Queensland Raceway, on Monday and/or Tuesday.
Temora, however, is located in the New South Wales Riverina region, around four-and-a-half hours' drive west southwest of Sydney.
How those teams would balance personnel between the two programmes, or whether it means they will fly straight down to Sydney or Canberra from Brisbane, is unknown.
A five-day Gen3 VCAT took place at Toowoomba's Wellcamp Airport last November.
