Sydney, Brisbane and Melbourne airports are seeing huge crowds this week as the country enjoys re-opened borders and the return of air travel for easter.
However, massive delays have been bought on by high demand, COVID-related staffing issues and what some airlines are saying is 'traveller unpreparedness'. It has caused some travellers to miss their flights.
Sydney Airport CEO Geoff Culbert told Channel 9, "our security company has 100 open roles they're advertising for at the moment, we're 30 per cent down on normal capacity, and that's leading to the problems," he told Today.
"We've got staff from all over the airport triaging and putting out the issues as they arise, but the reality is we're going to be dealing with this for a little bit longer.
"The unfortunate reality is we are going to see queues over the rest of the school holidays."
