Transport infrastructure construction dipping after long upturn - but still four more stong years before substantial downturn

This note provides a summary of Macromonitor's new report - Australian Construction Outlook - Transport Infrastructure. The report contains detailed forecasts of road, bridge, rail and ports construction by State, and by sub-segment.
Transport infrastructure construction saw its first year of decline this decade in 2024/25, with a drop of 4% in real terms. Prior to that, activity had increased by over 40% since 2020, and by 88% since 2016, to reach an all-time high in 2023/24.
Another small decline is expected in 2025/26, of around 2%, due to budget pressures on State Governments and capacity constraints in the construction industry.
Another upturn is forecast during 2026/27 and 2027/28, as the next round of major projects kicks in, returning total activity to around the 2023/24 level.
Some key projects over the next few years will include the Western Harbour Tunnel and M6 Extension in Sydney, Coffs Harbour Bypass, North-East Link in Melbourne, Bruce Highway Upgrades in Queensland and Torrens to Darlington in Adelaide.

A more substantial downturn is then expected to begin around 2030 as this last tranche of major projects moves to completion.
