Check put, Earthed (1 and 2), Synopsis, Drift and Drift 2: A new Race.
The drifts follow the Aussie Nationals racing scene along with some Aussie freeride, lets say that in Drift 2 there is a gap the Chris Kovarik says is too stupid and you'd have to be an idiot to hit.... This gap is huge and in single track trees, in the crash section you see someone fly into the trees next to the landing.
