Overview
- The Commonwealth added $229.6 million for design and approvals, lifting planning outlays to $659.6 million and formally starting the development phase.
- The business case forecasts $250 billion in long-run economic gains and about 99,000 jobs, with one-hour Newcastle–Sydney trips and services up to 320 km/h.
- Stage-one costs are estimated at $61.2 billion to reach Central Station by 2039, with about $32 billion more to extend to Parramatta and Western Sydney Airport by 2042, taking the corridor toward $90 billion.
- Public–private financing options will be assessed, though reporting indicates the federal government may fund most of the build, while NSW declines to commit money but offers to fast‑track planning.
- Infrastructure Australia flags low confidence in the housing uplift assumptions and warns benefits exceed costs only under favourable scenarios, as the Prime Minister signals the longer-term goal of a Brisbane–Sydney–Canberra–Melbourne network.
