1. EnviroX Consulting
Website: enviroxconsulting.com.au
Address: Unit 2/568 Darling St
Contact: 1300 599 996 | [email protected]
Hours: Available 24/7
EnviroX Consulting offer round-the-clock availability and same-day call-outs to handle critical contamination issues fast. Their in-house fleet of dust monitors, gas detectors, and drones makes tackling tricky terrain a breeze.
All of their asbestos assessors carry official SafeWork NSW licenses for total peace of mind. Every soil and air sample goes straight to NATA-accredited labs for highly accurate, legally defensible data.
On top of that, they’ll guide you smoothly through both preliminary and detailed site investigations to give you upfront cost certainty. Their local council-ready reports also help fast-track development applications across the greater Sydney area.
But know that they rely entirely on external labs for chemical analysis, so your wait times depend on third-party workloads. You’ll also need to hire outside contractors for actual lead removal, since they only handle inspections.

2. K2 Consulting Group
Website: k2consultinggroup.com.au
Address: Unit 304/56 Delhi Rd, North Ryde
Contact: 1800 523 000 | [email protected]
Hours: Monday-Friday, 9:00 AM – 5:00 PM
K2 Consulting Group commit to answering website inquiries within two hours, keeping your project moving without annoying delays. They also offer complimentary initial consultations to help you figure out your compliance needs upfront.
From there, the team develops practical, budget-conscious remediation plans tailored to your site’s specific conditions.
Their team packs serious academic punch, featuring engineers and scientists with post-doctoral Australian research backgrounds.
They manage everything from basic waste classification to complex groundwater testing across residential and industrial sites. For asbestos testing, samples are processed through NATA-accredited labs to meet strict New South Wales EPA requirements.
However, these strict testing procedures mean you can’t get instant on-site hazard clearances. Instead, you’ll need to wait for the official laboratory turnaround time before getting the green light.
The test results were professional
K2’s responsiveness has been excellent for the testing and follow through consultation. They replied with a quote and followed up with a phone call in a timely manner allowing me to schedule the work quickly. The test results were professional and in the timeframe promised. They answered my subsequent questions professionally with clarity around the result’s specifics and available courses of action. I am happy to recommend to my friends and associates.

Environmental Group Australia operates as a fully certified, carbon-neutral consultancy from the start. This green commitment is a massive plus if your corporate organisation is chasing strict sustainability targets.

If you’re buying a property, their easy-to-read due diligence reports can also take some of the guesswork out of a major investment.
But know that standard site investigations can take two to four weeks, which may be frustrating if you’re facing a tight property settlement deadline.

Contact: (02) 7258 2800 | [email protected]

NEO Consulting has a strong knowledge of the Greater Sydney Basin’s geology, so the team can quickly identify local pollution risks. The team actually hold triple ISO certification for quality and safety, adding confidence to their field assessments.
In addition, more than 50 local councils across Sydney have approved their environmental reports. They send soil and water samples to NATA-accredited labs, helping ensure submissions meet council requirements.

But keep in mind that urgent jobs may incur external lab surcharges. Also, a Certified Environmental Practitioner review must be specifically requested, as it isn’t included automatically.

I recently engaged NEO Consultancy to conduct an Environmental Site Assessment (ESA) for my fuel station. After contacting multiple companies, I was impressed by NEO’s competitive pricing and prompt service. The team demonstrated exceptional professionalism and friendliness throughout the entire process. On the committed date, I received my results. I had a great experience with NEO Consultancy and would highly recommend their services. For future environmental testing needs, I will definitely consider them again. 5-star.
