The next Australian national park could be designed by Minecraft fans, in a new project by the Adelaide and Mount Lofty Ranges natural-resources management board.

The South Australian State Government is inviting young fans to design their ideal national park via the sandbox game Minecraft.

The winning designs will guide the next national-park upgrades in the area, worth around $10 million. The competition is open for upper primary school students in years four, five, six, and seven in Adelaide and Adelaide Hills. Participants will be judged on their design's sustainability and realism. This could include bike trails, wheelchair accessibility, and campsites. To be considered, all entries must include five screenshots of their creation and a short three-minute narrated video clip of the scene.
