Your land may have been exposed to legacy practices that could present significant liabilities to your project and organisation. These liabilities can cost your project time and money, as well as affecting your corporate reputation. It’s vital that you consider your operating and site-specific conditions, regulatory requirements and stakeholder expectations.

Helping you minimise your risk

Whether you’re planning ahead or dealing with an accident, it’s important to take the right approach from day one. Our team will effectively manage any current or future issues, to minimise cost and to protect your corporate reputation.

Contamination issues can lower your property value and sink an otherwise profitable project through unexpected costs and extensive delays. To combat this, our team of specialists will provide remediation advice so you understand your options and get the best possible value for your land. If you’re purchasing land, it’s important that you don’t take on someone else’s liability. Through our understanding of the latest regulations, we’ll provide you with a clear picture and in-depth understanding of the issues at risk.

What we do

We can provide you with accredited contaminated land site auditors in your jurisdiction, for any market sector. Our accredited site auditors know how to meet the needs of each environmental regulator and the planning authorities.  We’ll make sure your contaminated land audit complies with the local jurisdiction legislation and regulations, and the overarching Australian guidelines.

You can use our independent auditors to:

  • review contamination assessments
  • monitor and assess remediation programs
  • audit the work of environmental consultants and remediation contractors
  • meet requirements for contaminated site audits by planning authorities
  • certify the suitability of your land for a particular use or range of uses

Our team

We have one of Australia’s largest groups of contaminated land auditors, all with more than 25 years contaminated land experience and most with more than 10 to 15 years’ auditing experience. We are represented in the accreditation schemes of Victoria, NSW, South Australia and Western Australia; and recognised by the local regulators as being qualified to undertake contaminated land audits in Tasmania, the ACT and Northern Territory.

    The sites I’ve audited range in size from a small urban residential block to a former cattle holding area covering several tens of hectares. The nature of contamination affecting sites has ranged from rubble from demolition of a residential house, to a former manufactured gas plant site. Other sites have included a school site on an uncontrolled industrial landfill and a public open air performance area in one of the oldest European settlements in Australia.

    I gained my auditor accreditation in 2008, which was based on almost 20 years’ professional practice in assessment, remediation and management of contaminated land. Most of my experience is in heavy industry, especially iron and steel making, mining industrial areas and downstream petroleum facilities at project locations across Australia, New Zealand, South East Asia and the United States.

    I enjoy using my experience to provide the project owner with a more assured outcome. The challenge I enjoy is gaining an understanding of the historical activities on a site so that subsurface contamination can be anticipated. This allows timely and cost-effective solutions to be implemented, as well as to reduce the impact of unexpected finds on the project program.

    Whilst there are many highlights, I’m particularly proud of an audit I undertook for a council owned gasworks. The site was demolished and sold for redevelopment, and medium density housing was built and occupied. Development on the adjacent property uncovered significant coal tar contamination which extended beneath the residential area. Council, as the party responsible for contamination, bought back the site and proceeded with remediation guided by their environmental consultant. I was appointed as site auditor near the end of the remediation works. We helped the council to identify an optimal solution for environmental controls which were affordable and could be implemented as part of the refurbishment of the housing. To enhance this outcome, Council was able to offer rental of housing to low mobility community members because the site was level and close to the centre of town.

    I’ve undertaken a wide range of audits covering many different land use types such as Defence facilities including munitions manufacturing, storage facilities and unexploded ordnance issues, former gasworks, petroleum storage facilities, former rail yards, vehicle component manufacture facilities, energy and water utility sites and works depots, pesticide manufacturing facilities, industrial sites, landfills, abattoirs, dredging projects, sports grounds and timber yards. Sites have ranged from small residential sized blocks to as large as 500 hectares. After 25 years working in contamination there aren’t many types of sites that I haven’t worked on.

    I was initially accredited as an Environmental Auditor by the Victoria EPA in 1997. Following this, I was amongst the first group of auditors accredited in NSW (in 1998), in Western Australia (in 2006) and South Australia (in 2009). I held my Victorian EPA accreditation until 2010 when I retired from that scheme. I’ve recently audited landmark development projects such as the $135M Glenside Mental Health Facility in Adelaide and the $1B Waterbank development, part of the Riverside urban rejuvenation project, on the banks of the Swan River at the eastern gateway to Perth.

    I enjoy the technical challenges associated with auditing. I particularly enjoy working on projects with challenging issues and looking forward to the possible audit outcomes to assess how to quickly resolve and close out the issue.

    I’m proud of the audit I successfully completed at the $135M Glenside Mental Health Facility in Adelaide. There were many challenges associated with this audit. As well as technical issues, the audit and project construction occurred simultaneously, and we had to work within South Australia’s new and developing auditing scheme. To combat these challenges, we had to make strong and quick decisions to avoid construction program delays. The audit was completed in 3 separate but overlapping stages. Each audit report successfully passed through the South Australian EPA administrative review without any comments or queries – which at that time was unusual. The audit contributed to moving mental health management in South Australia into the 21st Century, with the development of a new state of art mental health facility that is now open and servicing the South Australian community.

    My auditing experience includes both contaminated land audits and risk to the environment audits under sections 53X and 53V of the Victorian legislation. My contaminated land audits have covered a wide range of sites from small redevelopment sites to major Defence facilities with a wide range of complex problems. With a background in hydrogeology, my expertise is often drawn on for sites where groundwater issues are involved. In recent years I’ve focused on providing services to the landfill industry and have completed many audits relating to the construction of new landfill cells, capping systems and leachate ponds. I’ve also audited landfill operations that look closely at the landfill operational aspects and potential impacts to the environment.

    Initially accredited by the Victorian EPA in 1994, I’m one of the longer serving environmental auditors in Victoria with a wide range of auditing experience.

    I enjoy the technical challenges associated with auditing that require finding new solutions to sometimes complex problems. I also enjoy the human aspects that are always involved. As an example, I recently completed an audit for an overseas investor with limited understanding of both the regulatory requirements and Australian business practices. My client was in serious breach of their regulatory obligations and was under financial pressure from both the banks and their building contractors. By working closely, I was able to get this project back on track and the audit was completed successfully within the required timeframe. It was a winning result for all parties involved.

    I’m proud of all my auditing activities and it gives me great pleasure to see sites that were previously derelict now redeveloped and forming part of a new urban fabric. In particular, one of my landmark audits was the former Albion explosives factory site in Melbourne. The site was used for almost 50 years for the manufacture of explosives and was impacted by elevated concentrations of a broad range of contaminants, including explosives, aniline-related chemicals, nitrates and metals. The success of this project was based on a high level of co-operation between my role as the auditor and the site assessment and remediation consultant. My involvement extended from 1997 to 2000 over which time large areas of the site were cleared for redevelopment including residential areas, schools and commercial complexes.

    I apply my knowledge of less-commonly occurring soil and groundwater contaminants, as well as my background in aquatic chemistry, to provide smarter solutions to my clients’ land development and infrastructure projects. In many cases, these projects required development of site-specific criteria and assessment of off-site effects. I’ve audited over 90 contaminated sites, most of which have been former industrial sites with a complex history of manufacturing and chemical use, including seven former gasworks sites. I’ve also audited a number of former landfill sites to allow new uses to occur, including residential use.

    In 1997, I joined Coffey from EPA Victoria where I managed their contaminated sites team. I was closely involved in the development of contaminated land management policies in Victoria in the early 1990s and I’ve maintained this focus through my active involvement in professional associations. I’m a contaminated sites auditor in Victoria and until recently, in South Australia.

    I enjoy working collaboratively with clients and their consultant teams to efficiently resolve site contamination issues that arise in audits. I also enjoy being part of the team that successfully redevelops underused or blighted land.
