for a Healthier Harbour

ECOBEL is a not for profit restoring the health and bio-diversity of Sydney Harbour one project at a time.


Sydney's concrete foreshore to "Green"


Marine Harbour species under threat need saving

Amazing harbour for us to protect


We are a community group of volunteer scientists who are hands on replanting lost ecosystems and restoring the rich biodiversity of  Sydney Harbour and its surrounds.

As a registered not-for-profit we are run on the love of our volunteers and donations by our corporate partners.  

Why 2040?

An Intergovernmental Panel on Climate Change, a group of scientists, convened by the United Nations to guide world leaders, describes a world of worsening food shortages and wildfires, and a mass die-off of our oceans as soon as 2040 — a period well within the lifetime of much of the global population.

Over 50 % of Sydney Foreshore is concrete

As-well as mangrove re-planting we will endeavour to green Sydney's foreshore. In the tidal zone we help nature establish oyster reefs and beds of our native Sydney seagrasses.

5. Co-benefits for recreational fishing


Our Projects


Tidal Mangrove Nursery

Thanks to funding and support from Hunters Hill Council we are growing our Mangrove Tidal Nursery at Woolwich. We are growing 2-300 grey mangroves to replant along the Lane Cove River where the existing forests are getting lost to over development and ferry wash.

Cool Facts 

3 x carbon sequestering than trees

80 % habitats for costal fish stocks

Natural filters of heavy metals

Greening Berrys Bay

  • Establish and manage a tidal mangrove nursery (100 plants every year- 50 planted and 50 propogated)

  • Work with local council on a mangrove seed bank for endangered river mangroves

  • Plant out and green the concrete stonewall

  • return the biodiversity back to the bay both in, on and above the water

  • Engage and educate local community


Starts Oct 2021

Battery Recycling

Problem -Of the 9800 boat batteries replaced each year in the Sydney area approx 84% end up in land fill.  Each battery has 2-3 l of Sulphuric acid, lead and plastic all contaminate our ground water. Lack of waterfront  battery deposit locations , weight and low recycling price all contribute to them ending in landfill or on the seabed.

Solution- We will have dedicated drop off locations with a booking hotline. We would like to evolve the drop off points to include flares and fire extinguishers.


Awaiting Funding


Riverbank repair

A fantastic result was achieved at Woolwich baths when the lantana overgrown riverbank collapsed.

Work started with clearing the embankment and laying the geomembrane. Levis where then built and back filled. Finally the embankment was planted out with native grasses.

Protect Parramatta River Mangroves

In addition to the tidal nursery bio engineering works will be required to stabilise and protect the existing mangroves and salt plains


A second on shore nursery / Seed bank for the endangered river mangrove species will be established with further funding


Starts Aug 2021


Monthly Beach Cleanup

Come join us for a fun morning at a beach clean-up.

We have partnered with CLEAN-UP AUSTRALIA so we can keep a record of what washes up. Hopefully together we can make changes up the packaging supply chain.

ECOBEL holds the s 205 permit for mangrove rehabilitation.

A big shout out to the Department of fisheries for their support in our project. Their professionalism and support has been invaluable


The Global Mangrove Alliance is the chief custodian of the Mangrove Knowledge Hub for a global approach to mangrove conservation and restoration at a scale that matters.


ECOBEL is working with bio engineers and scientists to best improve the replanting results on a local level in Sydney Harbour. We are having great success with the natural coir hair sausage which protects the mangrove seedlings in the early stages of transplant.


ECOBEL is supporting  a restoration nursery to help grow out the River Mangrove (Aegiceras corniculatum )species  whose numbers are twindling .

Edible mangroves

Red mangroves have edible fruits, but they're quite bitter apparently. You can dry their leaves to make tea, too. The bark can be used...
