How much you prepare for and plan your trip will depend on where you are
going and how long you'll be away. A day's jaunt may be a spur of the moment
decision requiring little planning, and you may only need to take your basic
recovery gear, a fridge with a few cold drinks and lunch.
For an overnight trip you may plan where you could camp and what you would like
to see. As well, apart from the recovery gear and the fridge, you'll need a swag
or a tent plus sleeping gear, a bit more food and fuel.
On a trip up the Canning Stock Route or similar trips throughout Australia you
will need to do a lot more planning and take a heap more gear. Questions about
fuel requirements, and a dozen other things, need to be answered before you set
off. This aims to give you some idea of what you require, but you will need to
think about the trip you have planned, the style of camping and touring you
enjoy, and your gear. There are places where you shouldn't go if you haven't the
right equipment. While Cape York is fine without an HF radio, a more remote and
difficult trip like the Simpson or the Canning really demands at least one HF
radio in your group.
