A Gold Coast school was locked down twice in a day after a series of hoax threats.
Upper Coomera State College advised parents by text message at about 10.30am on Tuesday it had gone into lockdown.
The lockdown ended two hours later, with a police spokeswoman telling AAP the threat was a hoax and parents were given the option of collecting their children at the school.
But the school sent another message to parents at around 1.30pm another lockdown had been enacted.
It is understood the threats were made on Facebook on Monday night.
The profile continued to make threatening posts on Tuesday afternoon, after the initial lock down was lifted.
The state education department said the lockdowns were precautionary and were only lifted after police gave the all-clear.
"The Department of Education will always seek advice from authorities and in this instance the Queensland Police Service thoroughly investigated the matter and advised that there was no credibility to the threats."
It is the latest in a series of similar incidents affecting southeast Queensland schools in recent weeks.
Elanora State High School on the Gold Coast last week put out a statement playing down a risk to the school's population after two students had discussed a shooting threat by another pupil.
Separate bomb and shooting threats were made against a number of schools in the Gold Coast and Brisbane areas around a fortnight ago.
Three teenage boys were charged over the threats.
