Meet the site
Harry's Bommie is a Heron Reef site that begins at one large bommie, which marks the start of the dive, and then leads divers along a line of further bommies set among forests of hard coral. The dive's appeal is its unpredictability: each bommie has its own residents, and the guides like to say that you never know what will appear around the next one. The hard coral forests between the bommies are thick with damselfish and fusiliers, and the bommies themselves shelter a range of reef fish, crustaceans and invertebrates. Encounters listed by the dive team include a giant starry puffer, tawny nurse sharks resting on the sand, and brightly coloured nudibranchs on the coral heads. Turtles and reef sharks can turn up here as at any Heron site. The layout is easy to follow: a string of coral heads at moderate depth, so divers can choose how deep to go and how long to spend at each. That makes it a good site for mixed groups and for divers on their first few dives at Heron who want variety without complexity. Photographers will find plenty of subjects for both wide-angle images of the coral forests and macro shots on the bommies. Because the dive covers a fair distance, it is often done with a slight current, and the boat can collect divers at the far end if needed. The name should not be confused with 'Harry's House', a nickname for Turtle Gully linked to a great hammerhead seen there. Harry's Bommie was grouped with several other sites in the earlier database pass and is now listed on its own.
