From the ABC news:
"Last night the Department of Health issued an alert in relation to meningococcal disease," he said.
"A mistake was made when that alert was issued in that it had an embargo on it - it was not an active decision it was a mistake.
"It was an inadvertent mistake to issue it with the embargo on it, the media brought that to our notice straight away and we issued further information to the media to get the embargo off it."
I'm glad that's clear....
