Meet the site
Hamelin Island lies in Hamelin Bay and once carried a light station (built 1937 and moved to the mainland in 1967 as the Foul Bay Lighthouse). Marinelife.org.au describes a sheltered reef flat on the lee side in about 9 m, with ledges and small caves, and a long list of fish: prettyfish, bullseyes, pullers, buffalo bream, old wives, herring, pike, foxfish, leatherjackets, moonlighters and wrasse, along with gorgonian sea fans and colourful sponges.
That diversity in shallow, sheltered water makes Hamelin Island one of the better reef dives in the bay. The ledges and small caves shelter fish and invertebrates, and the gorgonians and sponges add colour. The NE Bommie off the island (listed separately) offers a slightly deeper alternative.
It suits Open Water divers with access to a small boat, and snorkellers on calm days. The main challenge is getting there: the Hamelin Bay ramp is narrow and swell-exposed, and conditions in the bay change quickly when the wind turns north-west.
Hamelin Bay was a timber port from the 1880s, when a jetty built in 1882 and extended in 1898 served M. C. Davies' milling operations. It was notorious for wrecks in bad weather because it is exposed to the north-west gales of winter storms; the 22 July 1900 storm alone wrecked several ships, and only the old jetty piles remain today. The bay is now a recreation zone in the Ngari Capes Marine Park, and every wreck in it older than 75 years is protected. Anchor on sand, never on the reef.
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
Hamelin Island is recorded as Island in Margaret River & Augusta. The listed access is boat (day trip). Confirm the actual meeting point, route and permission to visit; a map pin does not establish any of these.
Topics flagged by the stored research
These are questions prompted by the existing notes, not a verified or complete hazard assessment.
- Other water users
- Ask about vessel activity, exclusion areas and the agreed surface arrangements.
- Water movement
- Ask how swell and local exposure affect the proposed entry, exit and route.
Historical access notes exist for this record, but have not been independently verified for current use. Request current directions from the operator or site manager rather than following an old entry description.
Questions, answered
Is Hamelin Island suitable for my certification?

Can I book Hamelin Island through YouDive?
YouDive is an independent research directory. Contact an operator directly to confirm whether it currently runs the trip, the inclusions and the booking terms.
