The plans were lodged in February, but went before Lake Macquarie Council on Tuesday night.

The expansion includes the construction of two new hangar buildings and extension of the airport taxiway.

Both hangars are 50 metres by 20 metres and contain office and reception areas, meeting rooms, amenities and storage areas.

One of the hangars will also be decked out with a lift and two crew sleep-over rooms, a pilot’s lounge and viewing deck. 

A new internal car parking area accommodating 26 car parking spaces, with connection to existing internal vehicle access is also included.

The development follows the recent approval for a new terminal building and attached hangars.

The proposed works are located within an existing cleared grass area at the site, east of the Westpac Helicopter building, which also operates out of the airport.

Lake Macquarie Airport has been in operation for more than 50 years from the site, in a number of forms.

This includes former domestic passenger services, mail services, and private flights and operations.

In 2014 the airport was purchased by a consortium and is currently used for private aircraft services including skydiving and light aircraft. The site adjoins the Pacific Highway to the east and Lake Macquarie to the west.
