Why Australian Councils Are Paying More Than They Should for Infrastructure

A $1 preventive maintenance spend avoids up to $10 in future rehabilitation costs, yet most councils still wait for assets to fail.
Australian councils consistently underinvest in preventive infrastructure maintenance because the cost of deferral is invisible until it compounds into a much larger liability. IPWEA's 2025 Road Management Report found a 5% annual funding shortfall across 128 NSW councils compounds to a $3.3 billion liability over 20 years, while the national maintenance backlog exceeds $50 billion. Councils that shift from condition snapshots to condition trajectory data can time interventions before costs escalate, avoiding the liabilities building across the sector.
