If by chance you do plan on driving from Victoria to Queensland, I recommend drivers pace themselves (don't rush yourself and try to drive all night) and stop by Driver-Reviver Stations. I also recommend plastic bags for garbage and laundry, liquid hand-sanitizer and a couple of rolls of toilet paper. However, finding the right accommodations is often the most difficult, so these are accommodations I'd like to recommend:
River Park Motor Inn
Website: River Park Motor Inn
Location: Casino, NSW
Price: $86.40 (RACV or NRMA discounted price)
I would like to point out some things that might not be apparent at first.
~My trip wasn't during school holidays so accommodation was cheaper, make sure to check price-differences in comparison to peak season and off-season.
~With my trip, I worked on the principle of "Don't drive after dark". At about 04:30-05:00 pm you should probably start looking for a place to stay for the night.
~Victoria has RACV membership and drivers can use their RACV membership to possibly get a discount on their accommodation. However, New South Wales has NRMA and Queensland has RACQ, so drivers may need to verify if it's applicable.
~E-tag works in Victoria, New South Wales and Queensland, however if you don't have an E-tag, you can get a motor-way pass from the nearest petrol station. Make sure you tell them what state your car is registered in.
~Food expenses can add up over a trip, a simple cost-cutting measure would be to buy bulk-packs of water and snacks and store them in the car.
~Some motel rooms come with toasters and/or microwaves, so try to suss out what equipment you have in your room before you buy meals. If you can't heat it up in the morning, either don't buy it or purchase a smaller portion. Also make sure you have cutlery and/or plates if needed.
