Cairns is the city I went to in the northeast of Australia to go diving at the Great Barrier Reef. The city people call it a type of coastline, or Calafell Playa de Aro on the Costa Brava. There were a lot of tiny shops, many for boats or submarines, and lots of restaurants on the beach . What I have said a little Playa de Aro. It was the month of March, which is a very hot time in Spain, and Cairns is in a sub-tropical climate, so you can have an idea . For recreation, there is a big public pool in the middle of the city, in fact in the middle of the street. Do not go to the beaches, because they cost money, but not just on the beach.
