Sydney Airport Wetlands Bush Regeneration Project 2019-2023
Over multiple years, we restored key wetland habitats within the Sydney Airport precinct, balancing ecological rehabilitation with aviation safety requirements. Through our weed management services, we transform degraded areas into strong ecosystems.
| Clients: | Sydney Airport |
| Location: | Engine Pond East and West, Mill Pond, Mill Stream |
| Project Duration: | 2019-2023 |
Method & Technique:
- Bush Regeneration
- Broadscale Herbicide Spraying
- Aquatic Weed Control
- Planting
- Ecological Restoration
- Aquatic Weed Treatment
- Habitat Management
Project Outcomes:
We successfully completed a multi-year bush and wetland regeneration project for our client, Sydney Airport, spanning from 2019 to 2022. The project began with a focus on intensive primary works to control dense infestations of invasive species such as Cestrum parqui (Green Cestrum), Lantana camara, Chrysanthemoides monilifera subsp. rotundata (Bitou Bush), Ludwigia peruviana (Water Primrose), and various exotic climbers. These weeds were treated in staged sections to support effective restoration and site recovery.
Sydney Airport’s vision was to rehabilitate the riparian habitat around two wetland ponds, creating a functional and resilient natural area while minimising the risk of attracting large bird populations near the airport. Our team worked to achieve this balance by restoring native vegetation and managing habitat complexity appropriately.
From 2020 to 2022, we carried out regular maintenance works to consolidate earlier progress. Weed densities were effectively maintained or reduced across most work zones, with major improvements noted in Engine Pond West, Engine Pond East , and Mill Stream . Native vegetation showed strong regeneration, supported by our follow-up work and favorable seasonal rainfall.
In 2022, the final year of the contract, our efforts shifted to controlling vine and herbaceous weeds such as Rumex sagittatus and Anredera cordifolia, particularly in areas with good native cover or previous plantings. We also carried out supplementary planting to increase biodiversity, enhance habitat corridors, and reduce future weed re-establishment in cleared zones.
Throughout the project, a diverse range of native fauna were observed, including Striped Marsh Frogs, Eastern Water Skinks, Blue-tongued Skinks, Black Swans, Pelicans, Honeyeaters, Swamp Hens, and Superb Fairy-wrens — highlighting the ecological value of this urban stepping stone habitat.
This project was completed to a high standard, with all objectives met through careful planning, consistent follow-up, and strong teamwork. It stands as a successful example of large-scale ecological restoration in a complex urban setting.
