BRISBANE, May 23 - Police say a group of armed teenage boys confronted the man and his wife as they returned home from visiting colleagues on Saturday night.

The couple wasn't hurt but their government car was stolen and taken on a joyride before it was bogged outside the Cape York town. Three teens have since been charged.

The principal was also carjacked by a group of teens armed with an axe earlier this month - an incident that sparked the evacuation of 25 teachers on safety grounds.

Queensland Teachers Union president Kevin Bates says teachers have decided to remain in Aurukun for now, but warns further violence could change that.

"I think we are on the threshold right now," he's told The Courier-Mail.

"At the moment the teachers will stay in the community and further (safety) measures are likely to be introduced. But if there is another incident then I'd say that would be a strong reason for a rethink."

Northern Region Assistant Police Commissioner Paul Taylor told the paper the incidents had nothing to do with family or community tensions.

"This is an individual that has shown a great lot of commitment to the community, particularly in the education of the youth," he said.

"We don't believe that he is being targeted because of who he is, I think he has been targeted because he has been present when they are roaming around."

During the first carjacking two weeks ago, the principal was forced to hand over his vehicle when he went to the aid of other teachers concerned about youths loitering outside their school compound accommodation.

Residential security has since been upgraded, including better fencing and the installation of panic buttons.

The latest incident comes as a high-level government delegation arrives in the town for talks on Monday with Aurukun elders and community leaders.

The delegation, including the premier's own director-general, will meet with elders on Monday, and the government says the safety of education workers remains of paramount concern.

"I am told the school will remain open tomorrow and classes will resume as normal," Indigenous Affairs Minister Curtis Pitt said in a statement on Sunday.

"The officials will continue discussions with Mayor Dereck Walpo and importantly will meet with the women of Aurukun to hear first-hand their proposed solutions to unrest and the community's future."
