Boat Access

Keswick Island is easily accessible by boat via our mobile jetty, situated in Egremont Passage. When the jetty is available for use, an ‘open’ flag will be displayed.

The jetty is a 23 metre gangway attached to a 6×3 metre pontoon, and provides short-term drop-off/pick-up for most shallow hull boats (up to 12 metres in length). Tenders can be tied to the jetty for day use, provided they are not in the way of access for other boats.

Nearby moorings are currently unavailable and not in use due to cyclone damage.

The hours of operation of the jetty vary, depending on tides. Typically, the jetty is open for use 3 hours on each side of high tide during daylight hours, and longer (when possible) on weekends. Note that Keswick Developments Pty Ltd reserves the right to retract the jetty in the event of extreme tides or unsafe conditions.

The Keswick Kiosk, only a short walk from the jetty, offer coffee, snacks and buggy hire, and can assist with any queries.

If you have any questions regarding boat access to island, contact the Keswick Island Operations Officer on 07 4965 8043 or VHF Channel 12.
