Australia’s massive development boom has helped drive the economy over the past decade as it shifted away from the mining boom.

And as government’s invested in infrastructure to support increased population growth, especially with urban redevelopment in Brisbane, Sydney and Melbourne, the Australian aerial image and topographical survey company Nearmap has been flying over the nation, keeping track of how these major projects have transformed the landscape.

Nearmap has shared images from 10 game-changing Australian construction projects of the last 10 years with Business Insider, so you can see the impact they’ve had.

Here they are:

Barangaroo Reserve, Sydney

The NSW government announced plans to transform the former industrial port facilities on the north-western edge of Sydney’s CBD into commercial office space and recreational areas in 2003. When Barangaroo is completed in 2023, it’s expected to support around 23,000 permanent jobs, be home to 3,500 residents and contribute more than $2 billion annually to the NSW economy.

Brisbane Airport runway

The $1.3 billion, 3,300 m second runway will take around eight years to build on swampland parallel to the existing main runway.

Brisbane airport has more than 22 million travellers annually, and the new runway will increase the level of capacity to match the far larger Hong Kong and Singapore airports.

By 2035, the runway will create around 7,800 jobs and deliver a local economic benefit of approximately $5 billion annually.

The new Royal Adelaide Hospital

Adelaide’s main hospital, which opened in September, was built on 10 hectares in the Adelaide Park Lands on the north side of North Terrace. It cost around $2.1 billion, making it one of the most expensive Australian buildings ever built and has around 6,000 staff working there. The hi-tech campus has a fleet of automated robotic vehicles to help move supplies, meals and equipment around.
