Dividing WA's vast coastline into five distinct zones (Far North, Coral Coast, Shipwreck Coast, Perth and Great Southern), AQWA features a 98m underwater tunnel showcasing stingrays, turtles, fish and sharks. On weekdays, take the Joondalup train to Warwick station and then transfer to bus 423. By car, take the Mitchell Fwy north and exit at Hepburn Ave. The daring can snorkel or dive with the sharks with the aquarium's in-house dive master.
Diving costs $159 with your own gear (to hire snorkel/dive gear add $20/40). Another interactive option from Friday to Sunday is donning a wetsuit and breathing tube and negotiating an underwater seascape as a Reefwalker ($20).
