Everything you need to know about this dive site.
Dive Site Overview
Forming part of the Racha Noi landscape, Aussie Reef has long been a destination for day trip excursions departing from Phuket. Historically, the region was a popular entry point for beginner and novice divers due to its often clear waters.
Over the past 10-15 years, however, extensive coral bleaching events have impacted the health of its coral structures and marine ecosystems. Despite these changes, the site still provides a compelling drift dive experience. Divers will find extensive hard coral gardens in the shallower sections, transitioning to significant deep coral bombies as the depth increases.
The varied topography includes aspects of rocky reef and wall-like features, eventually sloping down to a sandy bottom that extends to around 35 meters, though recreational dives typically maintain a maximum depth of 30 m (100 ft). Navigating the reef usually involves a consistent current-assisted drift, making it an engaging experience for those comfortable with the flow. Exploring the terrain offers glimpses into an evolving underwater world.

Dive Experience & Conditions
Approaching Aussie Reef via boat, divers will typically prepare for a drift entry, aligning with the prevalent currents. Initial descent reveals clear, salty waters, often providing excellent visibility throughout the dive. The topography transitions from rocky reefs in shallower zones to deeper coral bombies, eventually meeting a soft sandy plateau. Currents are a significant factor here; they can be quite strong, frequently running directly to the south, which can lead to extended drift rides. Divers exploring the reef between 10-25 meters should remain aware of these conditions to manage their dive profile effectively.
Dive Difficulty & Safety Guidelines
Successfully navigating Aussie Reef requires an awareness of its currents, which can be robust and dictate the direction of your drift. While no specific hazards beyond general dive risks are consistently reported, managing your air consumption and no-decompression limits is crucial, especially when exploring the maximum depth of 30 m (100 ft). Dive operators usually select sites based on daily weather and current assessments, prioritizing diver safety. Always stay within your certification limits and be prepared for potential strong water movement.
