Fairly self explanatory.
Choose one option from Day walk and one option for Overnight.
Definitions.
Overnight means one or more nights sleeping in the outdoors while bushwalking. (not car camping)
Bushwalk means a planned walk through the bush for an hour or more. Taking a stroll through the local park on your way home from the pub does not count!

If you do not go on overnight trips choose the less than once every 2 years option.
