Heightened biosecurity measures enforced at Australia's international airports aimed at preventing the spread of ebola will continue indefinitely.
The security measures, which include the introduction of a new Travel History Card and temperature checks, were introduced this month for passengers arriving at major airports including Perth, Brisbane, Sydney and Melbourne.
As of November 18, 1336 people had been screened, with 36 undergoing further assessments, according to the Department of Agriculture.
None of those tested have required further treatment.
A spokeswoman for the Department of Agriculture said the measures will continue indefinitely.
"I believe we will be keeping these measures in place until such time as we're notified by the Department of Health that the outbreak no longer requires active border screening measures," she said.
"The measures in place have had a minimal impact on passengers. They are necessary to protect Australia and the health of Australians.".
Minister for Agriculture Barnaby Joyce refused to make apologies for the introduction of the security measures.
"Remember these measures are proportionate and have been introduced to ensure Australia has the best defences in place against this global threat," he said.
Similar measures were introduced when previous biosecurity threats loomed in the forms of bird flu and severe acute respiratory syndrome, or SARS.
A series of questions was sent to a spokeswoman for Perth Airport, including a request for further details about the implementation of the measures.
But the spokeswoman did not provide such details.
"Perth Airport is working with the Department of Health and other agencies to implement measures to reduce the risk of the Ebola virus entering Western Australia," she said.
The Australian Government advises Australians to reconsider plans to travel to Guinea, Sierra Leone and Liberia, where ebola remains a concern.
