There are plenty of diving facilities available all across Australia. There is a large number of excellent diving schools. Near any great diving spot, you will find all you need in terms of equipment and guidance.
Likewise, finding a good hotel and other touristic facilities should not be a problem around most of the popular diving areas. Keep in mind, however, that the quantity of facilities may vary depending on the area you’re travelling to. In Queensland, you will find an abundance of facilities for every taste and budget. This is also not a problem around the larger cities in other regions such as Sydney, Melbourne, Adelaide and Darwin.
In Western Australia and Tasmania, facilities are a bit more scarce, so booking ahead is recommended. Planning ahead is also definitely recommended if you’re travelling to some of the islands, such as Lord Howe Island and Christmas Island, as the number of facilities is limited. However, the facilities you will find are usually of great quality.
