Even if you're traveling on a budget, you're likely to consider renting a car for at least part of your trip to Australia. There are a few good budget car rental places and you might be able to get a vehicle for as low as $30 a day. Some places to check out include Wicked, Jucy Rentals, Hippie Camper, Travellers Auto-Barn and East Coast Car Rentals. Compare prices and confirm what's included before you commit.

In 2008, I travelled around Australia for a year with my 2 children and husband. When budgeting to do any kind of driving holiday in Oz, it is worth noting the huge variation in fuel costs around the country. Prices varied from $1.36/litre to the highest we had to pay of $2.72/litre at a roadhouse 100kms from Alice Springs. Once you leave the city, rural areas are very expensive to fill up. Cape York varied between $2 - 2.50/litre everywhere. Roadhouses also very expensive as they are out in the middle of nowhere. Fuel is a big consideration when preparing a budget as the distances in Australia are so long - particularly in W.A. Not so big a deal for independent single travellers, however, if you are travelling as a family and towing a caravan or trailer, you can practically see the fuel needle move before your very eyes! A great resource for anyone planning a driving holiday in Oz is a book called "Free Camping" - it lists all the free camps around Australia - most are just roadside stops with a toilet, sometimes BBQ facilities but many people stop so there is safety in numbers.
