Why dive here
With 129+ marine species recorded in the area - including blue sharks, blue whales, dolphins, dwarf minke whales and great white sharks - Lonsdale Bommies offers some of Victoria's richest wreck diving. Water ranges 13-20°C, warmest January, February, March.
Discovered and named by one of the great local diving legends, this dive site is spectacular. Approximately 1 kilometer from the Point Lonsdale Light and clear of the shipping channel, just outside Port Phillip Heads, is an amazing area of bommies, or underwater rock formations. Maximum depth: 17m. Average visibility: 10m. The strong current flowing this area has created a nutrient-rich environment and subsequently prolific marine growth and the associated marine life.
Safety Notes
