OK, for those who want to know how it happened ......................
I rolled it onto its side and then onto the roof in a mate's driveway 2kms from home just six days after returning from Madigan Trip last year. Just wanted to get some practical experience and photos of the theory we teach at the LROC Recovery Course about righting a rolled vehicle!!

"How can you roll a vehicle in a driveway?" I hear you asking.
Well this particular driveway is twice as steep as recommended maximum gradient, it was wet and mossy - still no problem for a Defender driving in low range and without using brakes .................................. however, when you have to turn slightly at the top and one front wheel drops off the side of the concrete and comes into contact with a wet railway sleeper, the vehicle becomes sideways very quickly. Still no problem for the Defender but the driver suffering a bit of surprise and shock at this stage didn't realise that low range reverse is still engaged so the high side rear wheel then climbs rockery .............. just enough to send vehicle on it's death roll.
I layed down across the front seats and didn't even suffer a bruise.
Righted it ourselves and then drove it home but due to extensive body damage the insurance Co wrote it off.
Was able to buy the wreck back as part of the settlement and also bought replacement vehicle -same colour and model - from Brisbane six days later. After all, I had another trip planned for two weeks later and one can't put off a trip to the bush just because of a roll over!!
