Last year, 64 international airlines flew over Australia’s airspace, operating 634,000 trips.
But now the skies are almost empty – as shown in these startling images from Flightradar24.
These pictures show the scene on a typical Saturday afternoon in February 2018 versus the scene at the same time and day in April 2020.
Meanwhile, these images were taken on Tuesday, 7 April over the skies of Sydney and Melbourne.
As March came to an end, Qantas, Virgin and the majority of international airlines paused nearly all of their international flights.
There are, though, some signs of life.
Qatar remains one of the few airlines to be committed to soldiering on throughout the crisis.
The airline will add an extra 48,000 seats on services from Doha to Sydney, Melbourne, Perth and Brisbane from 29 March until mid-April.
And on 6 April, the government announced it had struck a deal with Qantas and Virgin to resume limited repatriation flights to Australia from London, Los Angeles, Hong Kong and Auckland.
