Traveling with a dog in Australia is either easy or a nightmare.
I had my staffy for four years. First two years, I basically stopped taking holidays because the logistics of finding pet-friendly accommodation that wasn't either a sketchy motel or eye-wateringly expensive felt like too much effort.
Then someone told me to look at caravan parks instead of hotels and Airbnbs.
Caravan parks have been offering pet-friendly accommodations for decades because half their guests arrive with a dog in the back seat. I found caravan parks with powered sites where dogs are genuinely welcome, and not "tolerated for a $200 pet fee" welcome, actually welcome.
Took her to a park near the Murray River last autumn. She spent three days losing her mind in the best possible way. I spent three days sitting outside reading. It was the most relaxed either of us had been in a while.
The one caveat worth knowing: most parks have rules about dogs in cabins (usually not allowed) and school holiday restrictions on pet sites. Worth reading the fine print. But outside of those windows, it's genuinely the easiest way to travel with a dog in this country.
If you found anything else, please tell me, I'm always looking for new spots.
