Sydney faces major infrastructure and development decisions as city grows

Sydney is dealing with several major infrastructure and development projects at once. A new international airport is revealing its passenger plans, a massive underground tunneling project is underway, and there's a $2.7 billion proposal to fix a major traffic corridor.

At the same time, local issues are causing debate. The new Sydney Fish Market is getting mixed reviews, a harbor rezoning plan is worrying the maritime industry, and a legal battle over a council drain has cost a hospital tycoon millions. City leaders recently gathered at the Sydney Summit 2026 to discuss the city's future.
