The Queensland Building and Construction Commission (QBCC) has launched a new tool to identify the state’s riskiest suburbs for building defects. The Audit Mapper tool combines defect trends, licensee risk, and warranty data to direct inspectors to sites where issues are most likely to occur.
The tool has already led to over 4,000 proactive inspections, according to QBCC commissioner and chief executive Angelo Lambrinos. He said the tool gives inspectors and homeowners a clearer picture of where the risks are, allowing them to focus their attention on the most problematic sites.
The QBCC is using the tool to take a risk-based approach to regulation, with Lambrinos stating that high-risk builders who are over-represented in the top 5 defects will face closer scrutiny. This includes closer examination of site supervision and subcontractor arrangements.
Regional Risk Breakdown
The Audit Mapper tool shows that defect patterns vary significantly across different regions in Queensland. For example, between Cairns and Coolangatta, the most common Level 1 structural defects include roof cladding, internal wet areas, and wall cladding.
In the Gold Coast area, sites are more likely to have issues with wall cladding, roof cladding, and waterproofing. In contrast, Toowoomba’s common problems involve roof cladding, wet areas, and masonry. Lambrinos attributed these regional differences to varying environmental conditions.

Despite these differences, the data does not show a higher proportion of defects in any one area once weighed against the number of licensees operating there. The QBCC’s figures show that 98% of residential work is finished without a claim under the Home Warranty Scheme.
Regulatory Approach
The QBCC plans to use the mapping data to engage builders earlier where risk indicators repeat or escalate. Firms with a clean compliance record but operating in a flagged hotspot can expect the regulator to work with them rather than intervene immediately.
Lambrinos said this approach is a great opportunity for builders to proactively understand the heat maps and trends, allowing them to avoid issues like the top 5 defects. This works alongside the QBCC’s Compliance and Enforcement Strategy, which directs regulatory attention toward areas where the risk is highest and the harm is likely to be greatest.
Future Plans
With the Audit Mapper tool, the QBCC is taking a proactive approach to regulation, focusing on prevention rather than reaction. By working with builders and identifying potential risks, the regulator hopes to improve consumer protection and transparency in the building industry.
