The department can improve its oversight of maintenance contractors. 

Gaps in inspection coverage, follow-up and verification processes reduce the department’s ability to detect and address quality issues, particularly for routine maintenance.

Covered in this section:

The department’s approach to maintenance planning combines data modelling and visual inspections. This provides it with reliable, statewide insights into road condition and maintenance needs.

But the department does not always clearly document why it prioritises some sites over others or how it balances competing considerations.

Fragmented information and systems also limit its ability to identify the most cost-effective maintenance interventions.

Covered in this section:

The condition of the state road network continues to worsen, with a growing proportion of roads in poor or very poor condition. Renewal spending is not keeping pace with deterioration and defects are appearing faster than they are repaired.

The department’s public reporting does not provide transparency about road condition or the expected impact of maintenance works.

Covered in this section:

We made 6 recommendations to address our findings. The agency has accepted the recommendations in full or in principle.
