Limestone Caves and Turquoise Walls: A Small‑Group Dive Day off Rottnest
A seven‑hour private charter from East Street Jetty that delivers two guided dives around Rottnest’s limestone reefs—this guide explains the flow, limits, and what to expect.
Limestone Caves and Turquoise Walls: A Small‑Group Dive Day off Rottnest.
The waters around Rottnest Island turn a vivid turquoise and reveal reefs alive with schools of fish; composed of limestone, those reefs are riddled with caves and swim‑throughs that make every descent a compact exploration. On this small‑group private charter—aboard Linni—you’ll make two dives at carefully chosen sites, enjoy a hot shower and lunch on board, and benefit from a complimentary dive guide in a group capped at 12 divers.
