Families at an Adelaide primary school have expressed fear after a hidden camera was found strapped to a tree overlooking the school grounds. Police are investigating how long it had been there and who placed it, with the discovery raising serious safeguarding and privacy concerns.

The device was reportedly positioned in a nearby park or hill area with a view towards Hillcrest school. Authorities have not publicly identified a suspect or confirmed whether the camera recorded any footage, while families have called for reassurance and stronger security measures.
