Meet the team

On a holiday in another city, one of us solved a trail like this with their family. They came home and asked a question nobody could answer: why doesn't Sydney have one?

So a class of Year 5 students built it. Six months of afternoons on these footpaths — arguing over laneways, testing every code on their parents, cutting anything too easy. Nine chapters made it through, and the rest of the city is still keeping its secrets.
