TIH Consulting

Real advice, real support — right where you need it.

A Commitment to Practical Environmental Compliance

Helping businesses meet their environmental responsibilities through practical, on-site support, coaching, and straightforward compliance solutions.

About Me

I support clients across construction and development projects with tailored, site-focused environmental services — helping them meet compliance requirements efficiently and effectively.

I believe environmental compliance shouldn’t be a barrier, it should be part of getting the job done well. I’m passionate about working together to meet environmental obligations without blowing out the program or the budget.

I genuinely enjoy being on the ground, working with the people who know what’s happening on site. That’s where the best solutions come from. 

Hi, I’m Lorraine Dunmall, an environmental consultant based in Melbourne and a CPESC-certified specialist in erosion and sediment control.

  • Building Better in a Warming World: What Australia’s 2035 Climate Target Means for Construction

    It’s no secret the world is heating up, quite literally. The recently released State of the Global Climate 2024 report by the World Meteorological Organization confirms that 2024 may be the first year global temperatures officially breach the 1.5°C threshold, albeit temporarily. Sea levels are at record highs, oceans are warming rapidly, and climate-related disasters…

    The False Comfort of “Out of Sight, Out of Mind”

    My blog “The False Comfort: Out of Sight, Out of Mind” unpacks some of the things I’ve seen over the years when it comes to contaminated waste — the kind that quietly gets left behind, buried, or forgotten.

    It’s not always intentional, but these ‘out of sight’ issues don’t really go away they just wait…


  • Staying on the Right Side of the EPA: Lessons for Industry and Construction

    Seeing how the EPA enforces environmental rules is a useful reminder for anyone managing a project. It’s not just about avoiding fines—proper waste tracking, site approvals, and pollution controls protect your team, your reputation, and your bottom line. By learning from public enforcement cases and focusing on practical compliance, businesses can stay on the right…

    Are Your Sediment Controls Effective? Here’s What You Need to Know

    When was the last time you walked your construction site during or immediately after rainfall to observe where the dirty water is going? If you haven’t done this recently, it’s time to get out there. Sediment runoff isn’t just an environmental issue, it’s a compliance risk and community concern that can lead to significant fines…

    Why I Chose Consulting: The Human Side of Environmental Work

    In the past few weeks, I’ve been out connecting with civil earthworks teams around Melbourne, listening, learning, and sharing practical ways environmental support can add real value. This blog reflects on those conversations, my time with Fulton Hogan, and why I chose to step into consulting. It’s not just about compliance — it’s about culture,…

    Fast-Tracking EPBC Reform: What Renewable Energy Developers Need to Know

    If you’ve been watching the environmental approvals landscape in Australia, you’ll know it hasn’t exactly been known for speed or simplicity. But things are starting to shift. In August 2025, the government kicked off a process to fast-track reforms to the Environment Protection and Biodiversity Conservation (EPBC) Act, aiming to have new legislation introduced by…


  • There’s Something to Be Said About Proactive Enforcement

    What if the environmental regulator wasn’t the enemy but a project partner? In this post, I share real-world insights from the civil and construction industry and show how early collaboration between contractors, consultants and regulators can reduce costs, delays, and environmental risk while building stronger, more trusted relationships.

    Hidden Hazards in Melbourne Parks: A Site Management Reminder

    Last week, a seemingly ordinary garden bed at Newport Lakes Reserve in Melbourne became the focus of public attention after non-friable asbestos was discovered. While the area posed a low risk to human health, the discovery has reminded us all why proactive environmental management is important on every site. What Happened Lessons for Earthworks and…

    Case Study

    Even on sites that seem low-risk, heavy rainfall can quickly turn minor erosion or dust issues into major compliance and environmental problems. This case study highlights two recent construction projects I was on where proactive planning, improved erosion and sediment controls, and increased team awareness prevented more costly delays, reduced environmental impacts, and strengthened on-site…

“I had the pleasure of working with Lorraine on the Raising London Circuit project, where her environmental expertise directly supported improved sustainability outcomes onsite. Lorraine played a key role in increasing environmental awareness across the team and strengthening data capture processes, which significantly improved our ability to track and report on sustainability performance. Her collaborative approach and practical insight were instrumental in integrating environmental and sustainability goals into day-to-day site operations. Lorraine was an invaluable asset to the team.

Brae Haddock

Sustainability Advisor, Ineco

“As Project Manager on the Wambo Wind Farm civil works in Queensland, I worked closely with Lorraine on the civil infrastructure build where she demonstrated sound knowledge of Queensland environmental legislation and regulatory frameworks. Her ability to interpret and apply compliance requirements in a practical, site-based context ensured we met our environmental obligations during construction. Lorraine’s proactive engagement with the client and construction team, combined with her practical approach to on the ground implementation of erosion and sediment controls and environmental compliance, played a key role in the project’s environmental outcomes.”

Lawrenzo Van Hamond

Project Manager, Fulton Hogan, Wambo Wind Farm Stage 1

“As North Island Environmental Manager at Fulton Hogan, Lorraine provided practical and commercially-astute support to our field teams. This ranged from training material to on-site audits, always with the outcome in mind. ​Lorraine is passionate about helping up-skill those around her in environmental regulations and could be relied upon to provide robust guidance that could be relied upon. I would absolutely say that her hands-on approach and strong regulatory knowledge strengthened our long-term environmental management.”
