Two important milestones have been met, paving the way for the delivery of the Western Sydney Airport.

This week, the last remaining building was cleared from the site, completely transforming the 1780-hectare Badgerys Creek site into a construction zone. Preparatory works are currently underway – ready for early stage earthworks to commence before the end of the year.

Additionally, work to relocate 3.2 kilometres of an aboveground high-voltage power line that crosses the site to an underground cable route wholly located within the airport site officially commenced this week.

The work is being carried out by TransGrid, the manager and operator of the NSW transmission network.

This project is an Australian first for a 330kV transmission network, using an underground cable to connect two sections of aboveground cable on the same line. This is an innovative solution that supports the construction of the airport while maintaining a safe, reliable electricity supply.

This relocation is critical before the substantial program of works can commence, including moving 22 million cubic metres of earth.

These milestones mean the government is on track to deliver the airport by 2026.
