What you might see

  • DolphinPossible

Sightings are seasonal probabilities, not promises - even in peak season nature does its own thing.

Certification & difficulty

Open Water

Snorkelling

Not a snorkel site - Not typically snorkeled directly - this is the shark-cage-diving channel; the seal-snorkel activity is centered at Geyser Rock instead

Safety notes

Weather/swell dependent access (multi-day trip buffers often recommended); cold water; boat traffic concentration in a narrow channel; strong safety record (no shark-related injuries reported by area operators since 2005); no scuba diving conducted here

Permits & fees

Falls within the CapeNature-protected Dyer Island Nature Reserve Complex / Ramsar buffer waters; commercial cage-diving operators regulated under DFFE's shark cage-diving permit system and industry Code of Conduct

Permits and operators change - confirm before booking.
