Lee Breakwater and adjacent Nuns Beach form one of Victoria's most accessible temperate snorkelling and shore-dive sites. The 1,179-metre-long granite breakwater wall runs east–west, sheltering Portland Harbour while creating a rocky reef habitat draped in seaweed. Snorkellers enter from the sandy Nuns Beach on the northern side, swimming along the barnacle-encrusted wall where depths range from 2 to 14 metres. The rocky wall is alive with Bluethroat Wrasse, Senator Wrasse, Scalyfin, Moonlighters, and the occasional Weedy Seadragon drifting through seagrass beds. Australian Fur Seals and Little Penguins (at night) add to the magic. This is a superb beginner-to-intermediate site with easy shore access, though visibility typically sits between 2–5 metres due to port sediment and easterly swell stirring the water.

High risk: Restricted diving zone (inner harbour)
Recreational diving within the boundaries of the breakwaters of Port of Portland is prohibited without a prior permit. Diving from outer breakwaters also requires a permit.
Moderate risk: Fishing line entanglement
The breakwater is a very popular line-fishing spot. Broken monofilament and active fishing lines pose entanglement risks. Always carry a dive knife or line cutter.
Moderate risk: Boat traffic
The area is frequented by boats entering and leaving Portland Harbour. Snorkellers must display a dive flag at all times.
Moderate risk: Restricted diving zones
Recreational diving from the outer breakwaters is prohibited without a prior permit from Port of Portland. Diving beyond the pump house is conditional on the S.L. Patterson Berth not being in use.
Moderate risk: Fishing lines and hooks
The breakwater is popular with anglers; active fishing lines and discarded hooks, swivels, and sinkers pose entanglement and injury risks.
Moderate risk: Restricted diving zone
Recreational diving within the breakwater boundaries of Port of Portland is prohibited. Diving beyond the pump house requires a permit and is conditional on berth usage.
Low risk: Slippery rock entry
Scrambling down the breakwater rock wall is steep and slippery. The recommended entry is from the sandy Nuns Beach instead.
Low risk: Poor visibility
Visibility is often limited to 2–5 metres due to sediment from port operations and easterly swells stirring up the water.
Low risk: Easterly winds
Easterly winds create unfavourable conditions at this site. Best snorkelled when winds are from the west or south.
Low risk: Slippery rock wall entry/exit
Scrambling down the steep northern side of the breakwater is possible but the rocks are often wet and slippery. Recommended entry is from Nuns Beach.
Low risk: Reduced visibility
Port operations and easterly swells stir up sediment, often dropping visibility to 2–5 metres on average.
Low risk: Cold water temperatures
Southern Ocean waters are chilly year-round, typically 12–16°C, increasing the risk of cold shock and hypothermia without proper wetsuit exposure protection.
Low risk: Slippery rock wall
Entering or exiting by scrambling down the breakwater rock wall is dangerous as it is steep and slippery. Use Nuns Beach for safe entry/exit.
Low risk: Easterly swell reducing visibility
Easterly winds and swells stir up sediment, reducing visibility often to 2–5 metres. Best conditions occur with westerly to southerly winds.
Low risk: Slippery rock wall entry
Scrambling down the northern side of the breakwater wall is steep and slippery; entry via Nuns Beach is recommended.
Low risk: Easterly swell
Easterly winds and swells reduce visibility and stir up sediment; ideal conditions are westerly to southerly winds.
Low risk: Port operations sediment
Sediment from harbour operations can reduce visibility (often 2-5 m), especially after easterly swells.
Low risk: Poor Visibility in Easterly Swell
Easterly winds and swells stir up sediment from port operations, reducing visibility to well below 2 metres.
Low risk: Reduced visibility from sediment and swell
Port operations can stir sediment; easterly swells reduce visibility to 2–5 metres on many days.
Low risk: Restricted diving zones near port berths
Diving beyond the pump house is conditional and prohibited when the S. L. Patterson Berth is in use; a permit is required for diving from the outer breakwaters.
Low risk: Easterly swell & sediment
Easterly winds create unfavourable conditions and easterly swells stir up sediment, reducing visibility to 2–5 metres.
