Australia on Monday ruled out sending doctors to West Africa to help fight the Ebola outbreak because of logistical problems in repatriating any Australian who became infected with the deadly virus.

Doctors Without Borders, as well as the Australian opposition party have called on the government to send a medical team to assist in a worsening doctor shortage in West Africa, but Foreign Minister Julie Bishop said the Australian Health and Defense Departments had both advised that Australia could not safely evacuate Australian health workers back home.

“The Australian government is not about to risk the health of Australian workers in the absence of credible evacuation plans that could bring our people back to Australia,” Bishop told reporters.

Australia announced two weeks ago that it would immediately provide an additional 7 million Australian dollars ($6.4 million) to help the international response to the outbreak. The country had previously committed AU$1 million to the response.
