Hanging Gardens Diving
Hanging Gardens is a named wall dive on the Point Nepean side of Port Phillip Heads. Club accounts describe hanging marine growth along the wall, giving this destination its own character within the broader Nepean-side reef environment.
Current status
A named wall locality with position limits
The available historical location candidates do not yet support a sufficiently reliable locality marker. A map and locality-based weather are omitted until the position is better established.

Locality
The named destination
This guide describes Hanging Gardens at Point Nepean, Victoria. A Victorian Sub-Aqua Group account of a November 2018 trip names it as a separate dive destination. It belongs in the broader southern Nepean-side wall setting; the available evidence does not establish that it is another name for Nepean Reef or Sweep Reef.

Boat access
Access by boat
This is a boat-dive destination in the Port Phillip Heads environment. Confirm the named site, departure arrangements and current operating requirements with the skipper or dive provider. This guide does not specify a vessel route, drop point or mooring.

Site character
Hanging growth along a wall
The 2018 club account describes prominent growth hanging from the wall. A later individual dive account describes ledges and a richly covered wall. These observations explain the appeal of the named locality; they are dated visits, rather than a habitat survey or a promise of what will be present on a future dive.

Depth
Read the depth evidence in context
A 2025 first-person account records one Hanging Gardens dive at roughly 33 m. That is an individual observation, not a site maximum, standard depth or recommended profile. An independently established whole-site depth profile has not been recovered. Confirm the intended profile with the dive provider.

Conditions
Changing conditions at Port Phillip Heads
Tidal flow, vessel traffic and changing weather are relevant in the Heads environment. Atmospheric weather and dated diver observations do not measure underwater currents or visibility. Trip decisions require current local assessment by the operator; this guide supplies no tide windows, drop timing or safe-current threshold.

Protection
Marine park boundaries and protection
Port Phillip Heads Marine National Park includes protected areas around Point Nepean. The two unresolved Hanging Gardens location candidates return different results against the current official park polygon. The exact relationship of the named dive area to the boundary is therefore not settled here. Consult the current Parks Victoria maps and rules for the intended area. Fishing and taking or damaging marine life are prohibited within the marine national park.

Planning
Confirm the locality and intended profile
Confirm the intended destination, planned depth, experience requirements and current marine notices with the dive provider. Wall ledges and overhang descriptions are site context, not instructions for an entry route. The available historical location candidates do not yet support a sufficiently reliable locality marker. A map and locality-based weather are omitted until the position is better established.
