Besides New Zealand, travelers should stay out of the outback as well. Australia has one of the most diverse landscapes in the world. Deserts, rainforests, beaches, savannahs, snow and ice are all present. Australians want you to come visit, as they’re friendly and the continent is amazing, but their current policies are on track toward ruining the good thing they have. Kangaroo Island is one popular destination, but when developers attempted to boost tourism in the aughts with plans for things like a helipad and a golf course, the residents pushed back. Tasmania and the Great Barrier Reef are also both in danger thanks to overtourism, the latter being particularly at risk due to climate change.
