Julian RocksNguthungulli, commonly known as Julian Rocks, is a small nature reserve made up of two rocky islets sitting in the Tasman Sea roughly 2.5 kilometres northeast of Byron Bay. The reserve covers a large marine area and is managed to protect its rich underwater habitats.
The site is important in Bundjalung lore and was later recorded by European navigators in the 18th and 19th centuries. The rocks and surrounding waters are now part of a protected marine area that has had restrictions on fishing and exploitation since the 1980s.
For visitors, the attraction is the underwater life rather than the landform itself: clear walls, rocky bommies and channels host leopard sharks, grey nurse sharks, wobbegongs, many nudibranch species and seasonal whale movements. Dive operators and wildlife-spotting boats run short trips from Byron Bay to the rocks.
- Marine life aggregations: Dense schools, reef fishes and resident species such as leopard sharks gather around the rocks, making for exceptional sightings on dives and surface snorkels.
- Grey nurse shark habitat: Julian Rocks is one of a small number of critical habitats for grey nurse sharks in New South Wales, and divers often spot these large, gentle sharks.
- Humpback whale passages: From late autumn into early spring humpback whales migrate past the rocks and are frequently seen from boats between the mainland and the islets.
- Nudibranch and macro life: Rocky crevices and reef surfaces are rich in nudibranchs, small crustaceans and other macro invertebrates that attract photographers.
- Underwater topography: Dramatic walls, overhangs and channels around the rocks create varied dive sites with strong currents and depth changes.
Best Time to Visit Julian Rocks#

How to Get to Julian Rocks#
The nearest town is Byron Bay; most visitors join dive charters and wildlife-spotting boats that depart from Byron Bay harbour for the short crossing to the rocks.
Regional air access includes Ballina Byron Gateway Airport for the closest flights, while larger airports at the Gold Coast or Brisbane serve longer-haul connections; the last stretch to the islets is by licensed boat or charter from Byron Bay, so check operators and sea conditions before booking.
Tips for Visiting Julian Rocks#
- Visits to the rocks are by boat only - confirm whether your chosen operator is licensed for dive or wildlife tours and follows marine-park rules.
- Bring a windproof layer for the crossing and a rash vest or wetsuit appropriate to the season for diving or snorkeling.
- Expect variable sea conditions and currents - trips may be postponed for safety, so leave some flexibility in your schedule.
- Respect the protected status: fishing around the rocks is restricted within the marine reserve and sanctuary zones.
- If you want to see whales, plan between May and September when migrations are most active and mention whale-watching on your booking.
