Nurses coming to Australia on skilled migrant visas have come with suspect documents.

In 2006, four Zimbabwean nurses working in Queensland were caught with falsified certificates of good standing, a document needed to apply for work in Australia.

The certificates were issued by the Zimbabwean Nursing Board.

Three were found to have been genuine nurses who received their certificate earlier than they should -- but one was not. That nurse was deregistered.
