Australia is popular for quite a lot of things, including long stretches of pristine white sand beaches and unreal azure water and rock formations, famous architectural wonders and people, sprawling national parks with natural wonders and unique animal species like koalas and kangaroos. It’s a world-renowned surfing destination and home to the world’s largest coral reefs. Take city tours on the hop-on-hop-off buses or make a break for a tour of the vineyards.
