I remember Offroad nats at the same facility (99 i think it was) was well represented from the east, myself included as i was based in Penrith at the time (ran Castle Hill Off Road).
But hey all just my opinion and i can defiantly understand people wanting to see the worlds best race, again something i will do one day.
Its just a shame more people couldn't make the effort to come and race. Racing over here has changed alot in the past few years compared to what it was 10yrs ago when i first moved over here.
Enjoy Thailand mate
