Meet the site

Cigar Reef is one of the stranger sites in the marinelife.org.au Rottnest guide: a reef that rises to about 15 m from a 26 m sandy bottom and is described as a good place to find odd creatures. The guide also warns that it is an area of odd currents with variable visibility, cold currents even in summer and strange thermoclines. Those conditions probably explain both the unusual life and the site's low profile - it is not a charter site and very little else has been written about it.

The mixing of water masses around the north-west of Rottnest, where the warm Leeuwin Current meets cooler inshore and upwelled water, can bring species that are not seen on the sheltered reefs, and the sand around the base is worth searching for rays, flathead and other bottom dwellers. The reef itself supports the usual limestone-reef fish and sponges.

The guide lists the same GPS coordinates as North Point Hole, which is probably a transcription error, so the position here is left blank; confirm it with local divers before planning. The site suits experienced divers with their own boat who enjoy exploratory diving and can cope with thermoclines and changing current. Carry a thicker suit or hood than the surface temperature suggests, and plan conservatively for 26 m on air.

For most visitors it is a curiosity rather than a destination, but for macro enthusiasts willing to put in the effort, the unusual finds are the attraction. A torch is useful even in daylight.

Some details in this record need confirmation. Check the source information and speak with a local operator.

Research this site before booking

Cigar Reef is recorded as Reef in Rottnest Island. 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.

Current and timing
Ask how the operator assesses the current window for the actual route. Historical tide notes are not a departure instruction.
Lines and obstructions
Discuss any known entanglement concerns and the suitability of the planned area.
Planned depth
Confirm the intended route and training requirements; the recorded maximum is not a target.

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 Cigar Reef suitable for my certification?

The record lists Advanced Open Water. That does not establish suitability for every route or day. Share your training, recent experience and equipment needs with the operator and ask about the specific proposed dive.

Can I book Cigar Reef 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.
