The $2.8 million investment will be used to fund improvements to the airports taxiways and aprons to accommodate future air traffic and business owners.

Bathurst MP and Minister for Regional Transport and Roads Paul Toole said the investment will also accommodate current organisations who call the airport home, such as the Bathurst Aero Club, Central West Flying and WardAir.

"The airport has been a bustling hive of activity for a number of years, serving around 20,000 passengers annually," he said.

"It's critical for a regional centre like Bathurst to have an airport that can comfortably accommodate major events, future tourism and business opportunities."

The investment includes a $1 million contribution from Bathurst Regional Council.

NSW MLC member Sam Farraway said the investment acknowledges the importance of Bathurst's geographic location in attracting regular public transport [RPT] and private aircraft services.

"Council has done a great job at administering upgrades to this facility already, and this investment is another tranche of money to further stimulate the local economy," Mr Farraway said.

The funding is the first major investment for the airport since a joint $5 million commitment from federal government and council in 2015.

Mayor Bobby Bourke has thanked the state government for their continued support of vital projects in the region.

"This project is long overdue, and we'd like to extend our thanks to the state government for backing not only the airport, but local roads and water security projects as well," Cr Bourke said.

"There's real potential here to turn Bathurst Airport into one of the premier flight facilities in the state."

Councillor Monica Morse said the investment will provide growth in local jobs.

Bathurst Aero Club president John Nicoll said the opening of Sydney's second airport at Badgerys Creek will divert more small aircraft to Bathurst.

"When Badgerys Creek's control zone goes in, it will largely negate access to Sydney for small aircraft, and these upgrades will help us facilitate more visitors" Mr Nicoll said.
