OXFAM and Save the Children staff and volunteers dressed in protective gear at Riverside Park, Brisbane, to call on world leaders at the G20 to join together to get Ebola under control.
The protesters held clocks to highlight the short window of time available to get the killer disease under control.
Oxfam Australia chief executive Helen Szoke said there were 15 days left until the UN's 60 day window proposed to control the disease would end.
She said it was an economic, as well as a health, crisis.
The protest organisers said The World Bank had warned if the virus spreads neighbouring countries the economic cost could be up to $32 billion. - APN NEWSDESK
