As you are probably aware, Marino Cervini built Eastern Creek and Oran Park for GP3 also.
I'm not interested in doing a conversion for the track layout.
I was talking briefly to a photographer that did some fabulous shots of horizons of Bathurst and he asked about Eastern Creek Raceway. I was not able to stop thinking about it so I decided to research it a bit. It always was sort of on the list.
The earth photos are fairly clean up to date and there is lots of good reference material.
Thank you for the quick and interesting feedback.
