The existing Toowoomba City Aerodrome at Wilsonton in suburban residential Toowoomba has been historically restricted in development due to local council land development policy and poor local planning, although a runway extension in 2011 allowed for improved scheduled services with turboprop aircraft.

[citation needed] Construction on the site, a former quarry owned by the Wagner family since 1994, began in April 2013, with an ambitious timeframe for completion by October 2014.

[5] On 22 November 2013, a Beechcraft King Air owned and piloted by John Wagner became the first aircraft to land on the new runway.

[6] In June 2014, work began on sealing the runway and movement areas using EFC, a low-carbon cement-free concrete developed by Wagners, boosting the airport's green credentials.

[8][9] Regional services operated under contract to the Government of Queensland transferred from Toowoomba City Aerodrome to Wellcamp on 1 January 2015.

The Cathay Pacific 747 freighter aircraft made a brief stop en route from Sydney Airport to Hong Kong to collect produce bound for China.

[13] In October 2016, Cathay Pacific announced the opening of weekly cargo services starting on 22 November 2016, from Wellcamp to Hong Kong using a 747 freighter aircraft.

The service was a charter originating in Sydney before stopping at Wellcamp to collect 250 people traveling to Shanghai, China for a trade conference.

[19] This has subsequently required considerable consultation, and has been complicated by effective endorsement of the privately funded public airport development at all governmental levels despite potential impacts on the Department of Defence.

The airport location is also near the planned Australian standard gauge Inland Rail corridor which would link Melbourne with Brisbane, thus providing a potential road-air-rail hub.

[citation needed] In December 2014 the airport announced the development of an aviation education precinct, a joint project with the Airline Academy of Australia and University of Southern Queensland, to train pilots and offer courses in aircraft maintenance, engineering and electronics.
