  • Rocky headlands and promontories are prevalent with long sandy beaches between
  • Moderate to low ocean swell, with higher swells on the east-facing shores of Flinders Island. Wave height is highly variable. It is significantly higher on the western side of Wilsons Promontory compared to the eastern side that is protected from the dominant south-west ocean swell
  • High tidal range – up to 3 m. There are often strong tidal currents, particularly between closely spaced islands
  • Sea-surface temperature is representative of Bass Strait waters
  • The depth of water increases rapidly as you move away from shore
  • Granite reefs with smooth surfaces. Reefs have a dense and diverse cover of seaweed species, particularly coralline seaweeds, while deeper reefs have dense communities of sponges, sea whips and soft corals
  • The diversity of fish and seaweed species is high
