Overland track July `11

I am planning to do the Overland Track with a friend from the 7th to the 19th.
We have a 4 season tent, I have a pair of MSR lightnings and he is loaning a pair of Yowies.
We are leaving lot's of time to do it in case we get whited out and have an EPIRB and GPS.
Is there anything else I am missing?
