Sydney’s booming west will also be home to its own World Trade Centre (WTC), designed by global architect Woods Bagot and developer the Aerotropolis Group, which proposes four WTC towers.

The project, which plans for net zero carbon development, includes an international convention and exhibition centre, commercial space, an innovation centre for start-ups as well as retail and residential space.

An economic impact assessment by PricewaterhouseCoopers shows the mixed-use employment district at WTC Sydney would inject $13 billion into the economy, creating 43,500 direct jobs by 2040.

Aerotropolis Group chief executive Jomon Varghese describes the proposal, which aims to open by 2026 the same year as Badgery Creek Airport, as a social and economic contribution for the state.

"WTC Sydney is a project that will resolve the structural problem faced by Sydney by bringing balance to our city which is historically tilted to the east," Varghese said.

"It will create an ecosystem to promote international trade, economic activity and employment generation by connecting Sydney to the 322 cities in 90 countries through the WTC network.”
