Teggun,
The first "distance" problem would be the length of the runway... but since the OP is in Belmont, I thought I would have a stir.
I would bet $50 that it will be SYD-NAA. One of the senior management at Jetgo has been bragging to public servants for months that they already have the route.
Edit: I'll withdraw that wager (since nobody accepted it) - word from Narrabri is that they will be seeking presentations from both of the proponents before a meeting of the full council.
