MUCK-UP day glory for three VCE students who arrived at a Geelong private school in a chartered helicopter could be shortlived, with the stunt likely to land a huge fine.

The three Year 12 boys, who were dressed as Arabian princes, may also be prevented from graduating.

The Geelong Advertiser understands the Christian College students are now in serious trouble with the school and face thousands-of-dollars in fines because the helicopter did not have genuine authorisation to land on the Highton school oval on Thursday.

Sources say while the boys will be allowed to sit their VCE exams, which start next week, they will not be allowed to graduate from the school.

In a statement to the Geelong Advertiser, principal Glen McKeeman said: “Christian College confirms that a helicopter chartered by some students landed on the oval at the senior campus during celebration activities yesterday. The College has taken appropriate action with the students involved.”

Fellow Christian College students came out in support of the boys on social media yesterday, describing the chopper arrival as the best muck-up day prank ever performed at the school.

Geelong mayor Darryn Lyons also gave the boys a shout-out on social media, labelling them “all class” and #legendary.

It is understood excited students ran on to the oval, chanting the name of one of the boys, as the chopper landed.

Teachers and senior administrators reportedly looked mortified as the boys alighted, dressed in flowing Lawrence of Arabia style robes.

The theme of the school’s “celebration day” was “Living the Dream”, with students encouraged to dress up.

Asked if it knew anything about the incident, local helicopter company Geelong Helicopters said: “We will definitely be making no comment on that matter”.

Helicopters can be chartered in Geelong from Barwon Heads Airport for about $550.

Choppers that land without genuine landing permission can incur large fines, which are typically passed on to patrons.

The Geelong Helicopters website states: “Any landing by a Geelong Helicopters aircraft on public or private property where the client has provided unauthorised or fraudulent landing permission will be charged a fee of $2,500 (no exceptions), plus any fines or penalties which are associated with the unauthorised landing. This amount is payable by the client unless the unauthorised landing is due to an emergency or deteriorating weather conditions.”
