You need a dive medical for an Open Water Course (beginner level) and a Divemaster Course. You do not need a medical for an Advanced Open Water Course or a Rescue Course, however a regular medical examination is recommended (< 30 years or age: every 5 years, 30 – 50 years of age: every 3 years, over 50 years of age: every year).
The UWA Medical Centre (35 Stirling Hwy, Crawley, 9380 2118) conducts dive medicals. Alternatively, find a list of dive doctors at www.spums.org.au Prices for a dive medical range from ca. $50 - $100, so it is a good idea to call the doctors first to get a quote. The cost of the medical is not covered by Medicare or private health funds. (You are diving for fun, it's not a medical condition!)
The dive medical has to be conducted according to the Australian Standard AS 4005.1, which defines the requirements for a recreational scuba diving medical examination. The medical form you bring with you to the dive course must state that the examination was carried out according to AS 4005.1. We do not accept medicals which have not been conducted according to AS 4005.1!
