Project Outcomes:

Our team successfully improved all Georges River Hazard Reduction APZs and SFAZs throughout the 2023-24 contract period, meeting the objectives of reducing fire risk to neighbouring properties, lowering overall weed densities, and encouraging natural regeneration where possible. Hazard reduction activities and weed control works were carried out across much of the project areas, excluding the most dense weed thickets and the most resilient areas with minimal weeds or woody debris. We employed a range of treatment methods, including chain-sawing, brush cutting, skirting, hand-weeding, de-seeding, spot spraying, and cut/scrape and paint techniques, tailored to the species and locations, all with the aim of reducing bushfire risk.

Project Outcomes:

The 2021-22 bush regeneration project focused on reducing weed densities and encouraging native regeneration across multiple zones including areas containing remnants of the Sydney Turpentine Ironbark Forest (EEC). Maintenance included spot-spraying, hand-weeding, and the creation of habitat piles for fauna. We targeted key weeds like Ehrharta erecta and Bidens pilosa, particularly in areas with dense shrub growth and lawn interfaces. Flora surveys indicated reduced weed presence, with some notable results including the discovery of a small patch of orchids. Overall, the project improved native vegetation and reduced weed dominance, enhancing the site’s ecological health.

Project Outcomes:

Our team successfully managed vegetation along the Foreshore of Port Botany, including maintaining Saltmarsh in Penrhyn Estuary during the 2020-21 contract period. Weed densities were maintained or improved, thanks to our diligent efforts. We eradicated woody weeds in several areas, supported native regeneration, and reduced hazardous vegetation risks. All tasks were completed professionally and on time, meeting high standards. While ongoing weed management remains a challenge, our dedicated work and future maintenance will continue to enhance this vital ecological corridor for native flora and fauna.

Project Outcomes:

Our team successfully achieved the main objectives of Stage 1 of the contract period in 2023 by undertaking primary weed clearing within areas containing Eastern Suburbs Banksia Scrub, an Endangered Ecological Community (EEC). Using manual, mechanical, and chemical methods, we targeted dense woody weed thickets, vine weeds such as Asparagus aethiopicus and Rumex sagittatus, and herbaceous and grass weeds to support native vegetation regeneration.

In Stage 2 of the project in 2024, we conducted Secondary Weeding, spot-spraying, and Maintenance Weeding in Zones 1 and 2, effectively reducing weed cover to less than 10% across most of the site while monitoring native species regeneration. Additional weeding in new work zones, Var.1 and Var.2, further improved site condition by controlling woody, vine, herbaceous, and grass weeds. Our efforts enhanced the ecological integrity of this EEC, supporting the recovery of species such as Acacia sophorae, Solanum aviculare, and Stephania japonica. Continued Maintenance Weeding and spot-spraying are recommended to sustain these improvements and promote long-term native vegetation recovery.

Project Outcomes:

Our team has successfully improved all zones throughout the 2022-23 contract period, meeting key objectives such as reducing weed densities—particularly woody, vine, and herbaceous weeds—while encouraging native regeneration. We have enhanced the health of planted vegetation, increased species diversity, and improved habitat through revegetation and mulching.  Most weeds are now under control, with only Hydrocotyle bonariensis present in significant numbers. Buffer planting areas have seen a major reduction in weeds, though ongoing monitoring is required in southern sections. We have also prepared the Stage 2 and Stage 3 areas for future terracing, mulching, and planting, pending the removal of remaining Erythrina sykesii trees. Our continued efforts will ensure long-term ecological improvements across the reserve.

Project Outcomes:

The 1.84 ha Cooks River/Castlereagh Ironbark Forest project was successfully completed, improving site conditions while protecting biodiversity. Invasive vines and weeds were removed to reduce competition with native vegetation, and all weed material was collected and disposed of sustainably. Resilient areas were identified to support native plant recruitment, while coordination with the council ensured strategic plantings were implemented. Drainage channel banks were stabilised using jute matting and coir logs, and frog habitat was protected by avoiding herbicides and maintaining ponds. Erosion control measures were conducted, preparing the site for long-term resilience. Ongoing monitoring, collaboration, and community engagement are recommended to sustain these improvements. This project has enhanced bushland health and ensured long-term ecological sustainability.

Project Outcomes:

Our team has successfully improved the work zones at Bronte Gully, reducing weed densities and fostering strong native regeneration. We have effectively prepared areas for future revegetation, and many zones are in good condition thanks to our efforts. Despite occasional weather challenges, we maintained consistent control over weeds, ensuring ongoing growth of native plants. Our erosion control measures, including terracing, mulching, and planting, proved highly effective in stabilising slopes and preventing further erosion. Moving forward, we recommend continuing to extend erosion control strategies, applying mulch before weed germination, and selecting resilient native species to support long-term restoration.

We’ve been granted a 1-year extension contract, and our project at Bronte Gully is still ongoing. We’re excited to continue our efforts, building on the progress we’ve made so far and further enhancing the restoration of the area.

Project Outcomes:

Our team prepared the jute matting on the slopes for stabilisation after herbicide spraying to remove the lawn covering the ground. We also successfully completed planting work as part of the ongoing maintenance phase. This phase is progressing smoothly, with our team efficiently carrying out all tasks to support the continued restoration and regeneration of the area.

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.

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.
