Regional Express' Australian Airline Pilot Academy in Wagga has become a hub for international pilots to learn the ropes, with a particularly strong relationship to Vietnam.

However, as the Covid-19 pandemic forced international borders to close, the academy has not had a single international student come on board since February this year.

Head of the academy Chris Hines said the closures have left them concerned for the future of operations.

"We'd typically have well over 50 students per year join us, and had a cohort of about 35 students ready to leave Vietnam for our academy, but now are unable to do so," he said.

As the existing cohort begins to wrap up training, Mr Hines said the issue was a lack of replacements.

"We have no new customers at this stage to replace those soon to leave," he said.

"It's not just about the students though, it means our staff, many of whom are local employees from Wagga, may also feel the effect, and there will also be less students here to spend money in town."

Mr Hines feared the potential international clientele would begin to look elsewhere for training if the border closure remained in place for much longer.

"The longer this goes on, the greater the risk is that international customers will find alternative arrangements, and we've worked very hard to really strengthen that relationship over the last few years so we don't want to lose it," he said.

After speaking with government bodies at both a state and federal level, Mr Hines said he felt his concerns were heard, but hoped to see action taken.

"I certainly feel as though our local members have been very giving with their time and understand this particular case," he said.

"They have certainly expressed a desire to work with the NSW government to find a way around this."

Remaining hopeful, Mr Hines said change was needed sooner rather than later.

"If we haven't seen any sign or movement by February next year, things will get really tough," he said.

"We've got the existing cohort for now and have maintained operations, but by February we will potentially get down to having no students and we can't keep that up."

Wagga MP Joe McGirr said he had been in contact with the Deputy Premier's officer to garner support for the academy. He said the academy played a vital role in the region's economy, and should be a priority.

"I know the government wants to get the economy restarted, and the Deputy Premier particularly wants to get the regional economy back up, and this is a great opportunity to do just that," he said.

"The academy have doubled the rooms out there, they only just finished the work, so it's even more important that they have students through now."

Dr McGirr said exemptions should be considered for the Vietnamese students.

"Vietnam is a country who has controlled Covid very well, and the fact that Rex are happy to help provide support for quarantining means it won't cost the government to make those exceptions," he said.

"It's important to show they are still operating, the last thing we want is these potential students looking elsewhere away from Wagga."
