Meet the site
Back Beach Bommie is one of Bremer Bay Dive's shore-entry guided sites and, according to Marine Life Network, a 10-15 m dive with small marine life, sponges and corals, sea dragons and groper that is also a good night dive and an excellent photography site.
The bommie is a granite outcrop rising from sand, draped with sponges, encrusting and plate corals and ascidians and fringed with kelp. Seadragons – both leafy and weedy – are found in the weed around its margins, and blue groper and harlequin fish patrol the rock. The smaller life that makes Bremer Bay so good for macro photography is everywhere: nudibranchs, tube worms, basket stars, shrimps and crabs.
The dive is slightly deeper than the Little Boat Harbour trail and requires a swim from the beach to the bommie, so a guide is helpful the first time. At night, the bommie comes alive with crustaceans and octopus.
For visitors spending several days in Bremer Bay, Back Beach Bommie adds variety to the seadragon diving, and it is a useful option when wind direction rules out other sites. As with all Bremer Bay sites, divers should fill tanks and get the current advice at the dive shop before heading out. The shop's guides know where the dragons have been seen recently, which saves a lot of searching, and the modest depth allows long dives even in cold water if you are well insulated.
