A Gold Coast school has been locked down for the second time as police investigate another threat made against it.
Upper Coomera State College advised parents by text message at about 10.30am on Tuesday that it had gone into lockdown.
The lockdown ended two hours later, with a Queensland Police spokeswoman telling AAP the threat was a hoax and parents given the option of collecting their children at the school.
But the school sent another message to parents at around 1.30pm that a second lockdown had been enacted.
It is understood the threats were made on Facebook, with a user posting on Monday night plans to shoot students the following day.
The profile continued to make threatening posts on Tuesday afternoon, after the initial lock down was lifted.
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 students after two students had discussed a shooting threat by another student.
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.
