Upgrades for international passengers will include a longer baggage belt, more space for processing emigration and immigration, an expanded security screening area, more duty free shops and additional dining options.

Other additions include new lounges and VIP facilities for international arrivals and departures, a relocation of the Virgin Australia Lounge and a new “common user premium international lounge”.

The size of retail and dining space will increase by more than 80 per cent across domestic and international areas.

Builder Watpac has been chosen for the renovation works, which will increase the terminal’s overall size by 16,500 square metres.

Adelaide Airport said the expansion of the main terminal would help in its negotiations to attract new services with international airlines.

Managing director Mark Young said the project would ensure the airport was “fit-for-purpose” based on future growth forecasts.

“Since we opened the existing terminal in 2005, our overall passenger numbers have increased by close to 50 per cent. Our international numbers alone have almost tripled over the same period,” he said.

“This extraordinary growth means we need to keep growing our existing facilities. While we still have sufficient gate capacity to meet future forecast growth in the number of flights, we’re reaching capacity within the terminal.”

Minister for Tourism David Ridgway added the redevelopment would “enhance South Australia’s ability to attract more international airlines”.

“It’s certainly very encouraging to see private sector investment of this scale in South Australia,” he said.

Work will begin immediately, with the project completion date set for 2021.
