Perfect Sailing Conditions but there does seem to be a problem!

Two Rocks Marine Park has much more to offer than just two rocks. The park protects unique west-coast inshore lagoons; shallow waters teeming with colourful sponges, molluscs, crustaceans and fishes.

The lagoons provide habitat for young western rock lobsters, a crucial part of the marine food web and an important species for recreational and commercial fishers.

The diving in the park is astonishing.

The Swan River Traditional Owners have responsibilities for sea country in the park.

The park is 25 kilometres north-west of Perth and just north-west of the Western Australian Marmion Marine Park. It covers 882 square kilometres, with water depths from 15 metres to 120 metres.

The park has National Park and Multiple Use zones.

Explore
It’s easy and rewarding to explore the inshore lagoons along this part of the coast.

Dive tours, fishing tours and whale watching tours (in season) run from nearby Mindarie Marina.

Some of these tours visit Two Rocks Marine Park.

You can also explore the nearby Western Australian Marmion Marine Park, a diver’s paradise of lagoons, reefs and caves.

Discover
West-coast inshore lagoons are a feature of Two Rocks Marine Park.

These lagoons occur along the Western Australian coast from around Mandurah north to Kalbarri.

They run parallel to the coast, out to about 5 kilometres to 10 kilometres, and are protected on the ocean side by limestone barrier reefs.

The light-filled shallow waters of the lagoons support an abundance of seaweeds, seagrasses and marine animals.

The lagoons are key areas for species valued by recreational and commercial fishers, including:

Excess sea wrack (seagrass and seaweed) often accumulates along Two Rocks Beach, immediately south of the Two Rocks Marina.

The City of Wanneroo is currently in the process of investigating possible options to manage excess sea wrack accumulation in the area and would like to gain feedback from

community members and beach users on possible management options.

Sea wrack accumulation in Two Rocks is caused by the Two Rocks Marina, which interrupts the alongshore movement of both sand and sea wrack. The beach immediately south of the Two Rocks Marina has experienced ongoing sea wrack accumulation since the construction of the marina, particularly during summer months, resulting in issues with beach usability, public safety and odour.

In 2020 the Department of Transport (DoT) undertook a study which assessed the accumulation of sea wrack in Two Rocks and recommended that a Sea Wrack Management Trial be undertaken. The DoT Two Rocks Summer Wrack Accumulation Study (2020) can be found here.

In response, the City, in consultation with the DoT and the Two Rocks Yanchep Residents Association, conducted a Sea Wrack Management Trial in March 2022 which included the following:

Regular beach monitoring to identify when the deposited sea wrack becomes an issue;
Pushing of the deposited sea wrack back into the ocean using loaders on the beach during favourable weather conditions; and
Deployment of GPS drifters into the water with the sea wrack to track sea wrack movements and confirm that the wrack is removed from the beach area.
Unfortunately, during the trial, these methods did not achieve the desired results, we are now asking the community for their ideas on sea wrack removal for the area.
