GRID Autosport More Australian Tracks

How can we implement more Australian tracks into grid autosport ?
Because just having Mount Panorama is a bit soft, we need tracks like Sydney Motorsport Park, Townsville, Winton, Eastern Creek, Albert Park, and Sandown Park..... ?????
Anyway I've done some investigations into modding tracks from other games such as F1 2012 and i've had a look at the files from the Melbourne Albert Park circuit most of them are the same as the ones located in Grid Autosport so i think maybe a few minor tweeks and we could implement more tracks into grid.
But i will wait and see what types of files are in F1 2014 and we will go from there
