Dive-site story
Positioned beneath the sheer sandstone cliffs of Point Perpendicular in Jervis Bay, The Arch features a colossal underwater rock formation rising off the seabed. Divers explore the immense swim-through draped in encrusting sponges, ascidians, and sea tulips before navigating adjoining gutters and boulder fields. Oceanic swells can create noticeable surge through the opening, making buoyancy control essential as you drift past the shadowed walls.
Monumental natural sandstone archway draped in colorful sessile invertebrates
Frequent aggregations of resting Port Jackson sharks and wobbegongs around the base
Schools of pelagic fish patrolling the deep cliff drop-offs outside the arch
Location
Use the map to plan with your operator and confirm the exact entry point on the day.
Seasonality
Summer and autumn deliver warmer water and the most reliable visibility, though winter brings large aggregations of breeding Port Jackson sharks.
