The company behind a camp where a Brisbane schoolboy was critically injured on a high ropes course says it was a freak accident and had nothing to do with its equipment or staff competency.
Adventure Alternatives managing director Todd Samorowski defended his company's professionalism and safety after Connor Petterson, 14, became entangled in high ropes at Stanmore, north of Brisbane.
"This was an unforeseen incident," Mr Samorowski said in a statement on Thursday.
"It had nothing to do with the misuse or failure of any safety equipment, instructional or participant error.
"This incident also had nothing to do with our continued level of safety, our professionalism or the safety of any of the activities we run and will continue to run in the future."
They later issued another statement removing previous comments.
"It is far too early to speculate on why this occurred but please know we are determined to understand the causes fully and will do whatever is required to prevent something like this occurring again," the updated statement said.
Connor, a Marist College Ashgrove student, suffered facial and neck injuries on Wednesday morning and was flown to the Lady Cilento Children's Hospital in a critical condition.
He remained there in a critical condition on Thursday with his family by his bedside.
Connor's parents urged prayers for their son's recovery.
"Our son, who was involved in an accident while on a school camp yesterday, remains in hospital and is receiving the best of care," they said in a statement released by the hospital.
"Prayers for our son and our family would be greatly appreciated.
"We ask that everyone respects our family and friends' privacy at this time."
Mr Samorowski said his company was devastated by the accident, and they extended their best wishes to the student and his family.
Marist College Ashgrove cancelled the remainder of the four-day Year 9 camp and is offering counselling to students.
Workplace Health and Safety Queensland officers attended the campsite, near Woodford, on Wednesday and returned on Thursday to continue investigations.
Education Minister Grace Grace said the incident had touched parents and families around the state.
"This must have been a terribly traumatic experience for all involved," she said in a statement.
Ms Grace stressed any recommendations from the investigation would be implemented promptly.
"The safety of Queensland students is always paramount and we will leave no stone unturned to get to the bottom of how and why this incident occurred," she said.
