Australia has temporarily closed the door to people seeking humanitarian entry from Ebola-affected west African countries.

It's no longer processing any applications from the affected countries, which include Sierra Leone, Liberia and Guinea.

The government is also cancelling and refusing non-permanent or temporary visas held by people from Ebola-affected countries, who haven't yet departed for Australia.

Nineteen people from four west African families are currently in home isolation in Queensland after travelling to the state under a humanitarian programme earlier this month.
