It has prompted United Workers Union to make two referrals to WorkSafe since early June.

Union spokeswoman Lyndal Ryan said the organisation wrote to Canberra Airport managing director Stephen Byron requesting the airport meet with workers to discuss work place health and safety.

She said workers wanted to start a work health safety committee so they could raise concerns directly with management, instead of via the contractor that employs them.

But the union says it never received a response and is asking WorkSafe to intervene.

Security staff at the airport also say the contractor which employs them, Certis, has blocked them from attending the safety training they would like to attend.

The union has also asked WorkSafe to intervene in that matter. A determination is yet to be finalised for either matters.

"Our members at Canberra Airport have raised several concerns over the risks posed by COVID-19," Ms Ryan said.

"Complacency comes at a very high cost and as a community we must be assured that everything that could be done to ensure safety, is being done.

"It's one thing for the airport to say 'we want the airport open, we want as many flights as possible'.

"But it's not the managers at the airport who are facing customers day in day out. All [staff] want is to have a say in their safety, directly to management."

A Canberra Airport spokesman said as it does not directly employ security staff, who are contracted through Certis Security, it was not responsible for meeting with unions or staff employed by them.

The spokesman said shortly after the outbreak of the virus the airport established a COVID-19 sub-committee.

"A wide range of organisations who are active at the airport including Certis Security have representatives on the COVID-19 sub-committee. The committee meets on a regular basis and has already had 12 meetings," he said.

"All members of the sub-committee can raise any concerns their staff have raised at the committee meetings and the committee member organisations are encouraged to communicate the discussions/outcomes of these meetings with their staff."

A Certis spokeswoman said the upskilling and development of security staff was a priority for the company. She said the training program chosen was a registered training program approved by WorkSafe ACT.

"[It] was developed in consultation with our health and safety team as representatives of staff, and has proven to sufficiently meet the training needs of our staff while delivering the desired outcomes," the spokeswoman said.

"In addition to the regular training that Certis Security Australia provides, all staff have been provided with CovidSafe guidance materials in compliance with the Chief Medical Officer's advice."

The spokeswoman said it made personal protective equipment available including gloves, hand sanitiser and face masks to all employees.

"In addition to this, the Certis Security leadership team is progressing through the Australian government's online COVID-19 Infection Control training program."
