Thanks Dan & Petzi, it's a long story but the short version is, I binned it on a shitty piece of track in outback Queensland.
The tank was cracked open where it hit the road.
Touratech replaced the tank, saying that they felt it was a manufacturing fault and had not seen such a thing before.
The bike also needed a new subframe and a few other bits, which were replaced under insurance.
I managed to slice my left leg open with the bigfoot on the sidestand. It was not a pretty sight but I won't post pictures here, it may cause distress.
The Royal Flying Doctor Service flew me out from the medical centre at the remote Aboriginal community where they initially stabilized me.
I spent 6 days in Cairns hospital, then flew home.
The bike came home on a truck.
I go back to work tomorrow after 3 months recovery.
Its all good.
