I’m an Aussie living in the UK and I think you guys are incredibly lucky with your extensive and quality bridleway network.
Despite the size of Aus, there is very little riding in comparison, and most beautiful mountains are either on private land or in national park with forbidden access to mtb’s
I’m a Brit living in Oz, and I can’t speak for the mountains – not many of them around here – it’s all too blinkin flat 🙁 , but I’ve gotta say the Ozzies have a good attitude to coastline access.
Many other places I’ve lived/visited in Europe (tho’ not the UK – before anyone jumps to its defence!),Asia , and the US, allow rich individuals or hotels/golf courses to effectively, if not legally ‘own’ some of the best coastline and prevent the rest of us access to it. Here in Perth, there’s lots of public parks/open access along the coast, and anyone with a picnic blanket and a portable BBQ can have the prime spot on the beach, and the big houses with their swimming pools have to take second best!
