Dive Site Location & Key Facts
Dive Site Overview
Let's be straight about this one: it's not a standout site, and it earns its place mostly as somewhere to dive when the weather has closed everything else. With a southerly blowing, the wall offers enough protection to get a shallow dive in, reaching only about 3 m / 10 ft over a seagrass bottom.
What's there is a small wall and slope with nooks and crannies worked into it, the kind of shallow structure that gives a newer diver something to explore close to home. Baitfish move over the seagrass. It's a shore entry with parking nearby, so the logistics are easy. Visibility can be poor and the site is swell- and weather-dependent, so it shines only when conditions push you here instead of as a first choice. On the right day, though, it's a useful, easy shallow dive when nothing else is on. None of this makes it a destination, but on a day when a southerly has shut everything else, getting a shallow dive in close to home has real value. The small wall and seagrass give a newer diver something low-key to explore, with parking right by the entry.

Best Time to Dive
Summer and early autumn, with the best scores around January, February and April, give the most reliable conditions, though this site's real value is as a fallback when the weather is poor elsewhere. Water runs cool to mild, peaking near 23.8°C / 75°F and dropping to about 18°C / 64°F in winter, so dress for cooler water outside summer. The site works best precisely when a southerly is blowing, since that wind direction gives the wall its shelter. Wave height runs from about 1.5 m / 5 ft in calmer months toward 2.6 m / 9 ft in winter, and visibility can be poor, so this is somewhere you dive on the days that suit it instead of chasing a particular month.

Dive Experience & Conditions
Plan a very shallow shore dive at about 3 m / 10 ft, worked along a small wall and slope over seagrass. With depth this slight, it's effectively a snorkel-depth potter, so air and time are non-issues and the focus is the nooks in the wall. A torch helps you look into the crannies and read the structure when visibility is down, which it often is here. The shallow, simple layout keeps navigation easy. The point of the site is shelter, so you dive it when a southerly is blowing and better options are closed, accepting that the visibility may be modest. On the right day it's an easy, low-pressure dive close to Hillarys. Keep your buoyancy tidy over the seagrass and use the wall as your reference so you don't wander in the low visibility.
Dive Difficulty & Safety Guidelines
This is an easy, beginner-friendly dive at an open-water level, with very shallow depth and a straightforward shore entry. The honest caveats are more about conditions than difficulty: visibility is often poor, and the site is swell- and weather-dependent, so it's best dived when a southerly gives the wall shelter.
There's no overhead to manage, and the shallow depth keeps the profile forgiving. Keep your buoyancy tidy over the seagrass and carry a torch for the crannies and the lower visibility. Treat it as the backup it is, dive it on a sheltered day, and it stays a safe, simple shallow dive when better sites are out.
