Guys, thanks for all your comments and encouragements - need that. As I mentioned before I'm planning to cycle from Sydney to Perth Australia and am looking for advice on what to take luggage wise? I've made a list but there's always something!
The other thing is that I'm doing this with a t-shirt to make people aware (hopefully) of brain damage, which I aquired via a kite surfing accident. I lost a lung, got phnemonia, fractured my neck, spent 3 months in a coma and survived. So I'm aiming to prove a point to anyone afflicted by something as dramatic... ...it can be overcome. "f*ck you Brain Damage - you picked the wrong person!" kind of thing!
I've done bush walks and been bitten by Huhntsman Spiders so I'm OK with uncomfortability, but would like that equipment advice!
