A concerned community is receiving support after a 13-year-old's alleged "attack plan" on a primary school was discovered by counter terrorism police.
Authorities on Friday addressed local "angst", assuring residents of Maryborough, north of Brisbane, no further threats had been identified following the boy's arrest.
Local parents are reeling after the teenager was charged with possessing violent extremist material in preparation for what police alleged was a planned attack on a Maryborough primary school.
The boy was arrested after allegedly threatening people with a knife at a Maryborough business on May 28.
"I can only imagine how the parents of the Maryborough community feel at this moment," Superintendent Anne Vogler told reporters on Friday.
"We think that this is a type of offence that doesn't occur in our backyard but it has."
