You will be sent a series of clues which will guide you around Sydney on your smart phone/device. Once you get an answer correct you will be sent the next clue. There's a total of 17 clues and we expect it to take you 2-3 hours. Your team name and time taken will appear on the leaderboard at the end, but the clock will stop automatically every time you get an answer correct, so you can take your time and enjoy the trail. When you are ready to set off, just select ‘Next Clue’ and the clock will start again. Without giving too much away, you'll work your way across the city ending in the Botanic Gardens near the Conservatorium of Music.
