At 7:00 am Beneath The Bay’s Double Dive launches from the Mosquito Bay Boat Ramp in Lilli Pilli, Long Beach, New South Wales, offering two guided dives across the protected reefs and island outcrops of the Eurobodalla coast. This four-hour trip suits certified divers aged 12 and up who want close encounters with sharks and dense marine life in clear, chilly temperate waters.
The day begins with a punctual meeting at the boat ramp; by 7:30 am you board the Beneath The Bay vessel and head out to sites like Tollgate Islands, Black Rock, Burrewarra Point, Jimmies Island and, on rare days, Brush Island near Bawley Point. These sites are characterized by rocky reef shelves, vertical walls and kelp-studded bommies that host soft corals, encrusting sponges and schools of leatherjacket and snapper. Divemasters guide both dives, typically 45 minutes each, and manage descent profiles so you can focus on the scene below: curious sharks both large and small, hunting rays, and dense fish life that picks through crevices.
What makes this offering stand out is the combination of intimate group sizes (maximum 11), fully guided dives and local divemasters who read conditions and choose the best nearby reef on the morning. The itinerary balances adventure and safety: surface intervals back at Mosquito Bay give you time to warm up at the boat-ramp café, change tanks, and swap notes before the second plunge. Gear hire is available onboard, from 7mm wetsuits to regulators and dive computers, and you can opt for Nitrox if you plan deeper or repetitive profiles.
Practical requirements are clear: show Open Water certification (or equivalent), be at least 12 years old, and have recent diving experience or a refresher arranged through the operator. Expect rough weather to dictate sites; the operator requires a minimum group size to run. Post-dive protocol includes a 24–48 hour no-fly window to reduce decompression risk.
Why book this trip? For divers visiting the South Coast who want real, local-led encounters with temperate reef ecosystems and clinically run shark encounters, Beneath The Bay’s Double Dive squeezes maximum underwater time into a fast, certified-friendly morning. It’s an efficient way to sample multiple sites, see species unique to NSW’s coastal shelves, and return to shore with clear dive logs and strong memories.
Book in advance during holiday weekends and school holidays when dive slots fill quickly; Beneath The Bay generally asks for at least six divers for departure, so private groups improve the chance of a run. If you haven’t dived recently, schedule a scuba refresher with operator to review buoyancy and emergency procedures. Surface conditions can change fast; pack seasickness remedies, a warm jacket for the return and reef-safe sunscreen for the surface interval.
