Covid-19 detector dogs have been employed at Adelaide Airport in the hope the canine crew could one day protect Australian borders from the deadly pandemic.
A trial began on Thursday and is the next stage of ongoing research into the effectiveness of the dogs detecting the virus excreted through sweat glands.
The six dogs, provided by the Australian Border Force (ABF), SA Metropolitan Fire Service and University of Adelaide, will be tested on travellers returning to Australia on repatriation flights.
It comes after a Sydney trial where dogs were monitored for effectiveness in detecting Covid from sweat samples of infectious people.
