Aquarium Reef 1
Geraldton, Australia
Aquarium Reef One in Geraldton offers a decent surface swim to reach the dive site. Once there, keep the reef on your left as you swim out. You'll encounter a swim-through cave; stay close to the bottom and follow the sand. The cave is only 5-8m long and has holes in the roof, but they are not large enough to exit through. Continuing along the reef as it starts to break down will lead you to the right and towards a second reef.
