JWA Pty Ltd has been involved with many projects of varying complexity, completing over 1000 in South East QLD and on the NSW North Coast, since 1997. We have experience in the assessment of impacts on flora and fauna resulting from a wide range of development types including: residential developments, mineral extraction, tourist development, environmental facilities, roads, power lines and infrastructure, and agricultural and horticultural operations.

Some of our completed and current projects are presented below:

Mining and Infrastructure

James Warren has prepared a number of Mining Rehabilitation and Environmental Management Plans (MREMP’s) for gold mines and sand mines in New South Wales. James implemented various monitoring and reporting programs at the Woodburn Mineral Sands mine at Newrybar near Lennox Head. James also completed a number of Annual Monitoring Reports for gold mines in Parkes and Blayney (near Orange).


The Kingscliff Resort is an eco-tourism development proposed by Leighton Properties on the environmentally sensitive coastal Crown land known as Lot 490, Kingscliff, Northern NSW. The resort site is located between Cudgen Creek and SEPP 14 Wetlands, and Bogangar Beach. JWA completed an initial Ecological Constraints Assessment and then a more detailed Flora and Fauna Assessment.  We subsequently developed a Vegetation Management Plan outlining management strategies for the retained vegetation and the rehabilitation of the adjacent riparian and dune areas.

Crystal Creek Rainforest Retreat, adjacent to Numinbah Nature Reserve, is extending their current facilities with 6 new mountain lodges. JWA conducted an Ecological Assessment on the proposed site. Vegetation recorded included both wet sclerophyll and rainforest with three threatened flora and two ROTAP species. Although the environmental impacts of the new lodges will be low, and major vegetation rehabilitation on the former banana plantation is ongoing, the mitigation measures outlined in our report, including weed control and plantings of local native species, will be undertaken.

Residential Development

Urliup Road, Bilambil, Northern NSW is a 52 Lot residential development proposed, by Plateau Nominees Pty Ltd, on a site previously used as a quarry. The site is highly disturbed and weed infested. The design of the residential layout is sensitive to the adjacent riparian zone of Bilambil Creek. JWA conducted an Ecological Assessment and prepared a Riparian Management Plan outlining strategies to restore the area to a pre-quarrying state. An extensive weed control strategy was developed to remove the dominating exotic camphor laurel and to replant the area with riparian rainforest species.  The plan also included the translocation of the threatened species, the Rough-leaved Queensland nut (Macadamia tetraphylla).

Cobaki Lakes Estate is a residential development, proposed by LEDA, on 593.5ha of land within the Tweed Shire in Northern NSW.  A variety of housing, a town centre, a private school, a childcare centre, JWA has been involved with the project since 1993 and has just completed an eight volume report comprised of an Ecological Assessment, Saltmarsh Rehabilitation Plan, Scribbly Gum Management Plan, Regeneration and Revegetation Plan, Fauna Management Plan, and Wetland Rehabilitation Plan.  JWA have completed a number of specialist reports dealing with old growth tree and tree hollow replacement strategies. JWA are currently locating offsets for freshwater wetlands and Swamp sclerophyll forest which is to be lost during the development process. 

Kings Forest is a residential development of almost 10,000 lots near Kingscliff, Northern NSW. Integral parts of the development are an 18-hole golf course and 266 hectares of open space. The concept plan, proposed by LEDA, has been approved by the Minister for Planning under Part 3A of the NSW Environmental Planning and Assessment Act 1997. After extensive ecological investigation, including a Species Impact Statement (SIS) prepared by JWA in 2000, the site was declared of ‘State Significance’ in 2006.  JWA recently completed an Assessment of Significance required under NSW State legislation (TSC Act 1995) on 6 flora and 25 fauna species recorded on the site. Five of these (i.e. 2 flora and 3 fauna) were also assessed under Commonwealth legislation (EPBC 1999).   We are currently completing Buffer, Threatened Species, and Weed Management Plans for Stage 1 of the development. Extensive negotiations have been carried out with the Commonwealth, NSW Planning and Tweed Shire Council in order to ensure that all conditions are compliant with each agencies approval.

Peregian Springs and Coolum Ridges are 2 large residential developments in South East Queensland. Forrester Kurts Properties Pty Ltd (FKP) engaged JWA to prepare a translocation plan for a portion of the population of the Endangered Emu-Mountain She-oak (Allocasuarina emuina) located within the Peregian Springs development site. A plan for long term site management was developed, including weed and fire management, and monitoring of translocated plants. FKP also commissioned JWA to prepare a report stating compliance of the conditions of three Commonwealth approvals for the Peregian Springs and adjacent Coolum Ridges development sites.
