ABC's subsidiary channel for pre-school programs, ABC4kids has snapped up the 2012 special for broadcast at the start of April.
Mystery's critical and commercial success was realised when it was named the UK's No. 1 Pre-School DVD of 2012 last month.
Blue Mountain Mystery: The Movie makes its Australian terrestrial debut on ABC4Kids on Easter Monday at 5pm.
Thanks to Thomas Stansfield for the alert.
