Mate of mine had a huuuugeey doing some local shuttles and had to get airlifted off the track. Dude was off the bike for a good few months and while getting his bike sorted out for his first ride back noticed a decent crack in the top tube. Insurance paid up as it was the result of an accident...
I camped on site in my van when I raced at GV last time. They were pretty accommodating. Water and toilets on site. Coffee cart etc. Short drive to albion park/shellharbour to get food. Beach isnt that far away for a revitalizing cold public shower.
I raced an enduro there in 2020. The walk up is pretty tough, especially if its warm. Great tracks though. Some pretty flat out parts, plenty of braking bumps and jump lines everywhere. The sheer amount of flies was brutal. Wasn't particularly rocky.
$117 for DMR vaults isn't too bad if you've got a few other bits and pieces to get over the $179 free shipping threshold - https://www.chainreactioncycles.com/au/en/dmr-vault-v2-exclusive-flat-mtb-pedal/rp-prod202930
