Travellers heading in and out of Canberra airport are facing significant delays after an electrical fault closed the airspace.
Early flights were unable to take off and limited flights arrived on the tarmac on Thursday morning.
Just two of the eight flights that were scheduled to depart before 9am made it into the air with delays expected to carry through into the morning as the backlog is cleared.
An Airservices Australia spokesperson said the delay was a safety precaution after an issue with radio frequency in the air control tower was detected.
“An electrical fault at our Canberra Airport Tower impacted our radio frequencies,” the spokesperson said.
“There was no radar issue.”
The spokesperson added that safety is the Airservices’ “number one remit”.

The issue was resolved by on-site electricians and radio frequencies restored just before 9am with flights now able to arrive and depart from the airport.
A passenger shared his frustration at the delays on social media saying it looked like a long wait ahead.
“Looking like a long day, Canberra airport currently closed,” he tweeted just before 7am.
