As was said above fuel is your biggest expense so the trick is to not to go too far each week - just amble along & stop for days at a time. If you do get short of cash before pension day have what is known as CUP days - just sit tight in a free camp spot & Catch Up Pension. Just make sure you havee money put aside for rego, insurance & a litle bit for emergencies
You could do some volunteering which often supplies facilities for caravaners. We looked after a police museum in Timber Creek NT for 3 weeks. It provided a toilet, water & power and nothing but 3 large boab trees for neighbours. Opening hours were up to us(within reason). It was one of the most relaxing peaceful stops we had & we managed to save some money while there as well.
There are many places looking for temporary caretakers that are perfect for grey nomads. Check the volunteer section of this site or just ask other nomads.
Another suggestion, though there is an initial $60 outlay for their book (that was two years ago) is 'Willing Workers On Organic Farms' http://www.wwoof.com.au/
For 2 to 6 hours work a day (depending on the place) you get free power, water, facilities & even food depending on how long you work for each day. Many young people from overseas like to do this to keep their Australian stay going but, we found many places prefer the older nomads because we don't have to have things explained as much & they find us more reliable.
Anyway, good luck in your travels
Cheers
Jon

I fully intend to do it on a pension, but I do have some savings behind me for emergency repairs, rego & insurance. There are plenty of beautiful spots where you can just chill out and wait for the pension to come in. I guess it all depends whether or not you have any other commitments, such as a home base etc., then I think it would be difficult. But hey! nothing ventured nothing gained as they say. Give it a go, you only live once!
