How much does a contaminated land assessment cost in Queensland?
There is no reliable one-price answer. The cost is usually driven by the question the assessment must answer, the site history, investigation scope, sampling needs, access, laboratory analysis and whether regulatory or auditor involvement is required.

Start with scope, not a headline price
A useful quote should be tied to the property and the decision you need to make.
Past activities
Former fuel storage, workshops, industrial activity, waste handling or other notifiable activities can change the investigation strategy.
Desktop review vs field work
A desktop/site-history assessment is different from intrusive soil or groundwater investigation and laboratory testing.
SQP and auditor roles
Queensland requires a suitably qualified person for specified contaminated-land functions, while documents submitted to the department require approved-auditor certification.
Information that can improve a quote
Provide the address and lot/plan if known, the reason for the assessment, current and historical use, EMR/CLR information, previous reports, development or transaction deadlines, and what outcome you need.
Queensland Government guidance recommends discussing objectives, scope, site characteristics, site history and available contamination information with the suitably qualified person, and considers obtaining several quotes good practice.
Cheap is not always comparable
Two proposals can have different assumptions, sampling density, laboratory suites, reporting deliverables and exclusions. Compare the scope and intended outcome—not only the total price.
A poorly scoped assessment can create additional work later if it does not answer the transaction, planning or regulatory question.
Need a contaminated land consultant in Brisbane rather than general cost information?

When costs can increase
Common drivers include multiple potential contamination sources, groundwater investigation, difficult site access, deeper drilling, disposal or remediation planning, repeat sampling, validation work, tight deadlines and independent auditor involvement.
