The weekly challenge: Australia-wide.

You're looking for a weekly challenge, a real cash prize treasure hunt, right here in Australia. Specifically, on the streets of Melbourne. Hub 4 brings you a city-wide Melbourne treasure hunt game every single week. It's a proper hunt, not a lottery. Your city is hiding money. We know where. This isn't about luck. It's about knowing Melbourne, solving a clue, and moving your feet. Every week, we hide a physical Hub 4 sticker somewhere in the city. Your job is to find it first, prove you're there, and claim the prize. This whole operation is owned and operated by Synap AI Pty Ltd (ABN 86 695 003 653 · ACN 695 003 653).

How the Melbourne Treasure Hunt Game Works

Playing Hub 4 is straightforward. You get a clue. You solve it. You find the token. You answer a question. You win. There are no draws. No random elements. Just skill. Each hunt starts with a fresh clue landing in your member portal. This clue points you towards a hidden Hub 4 sticker. It could be in a park you thought you knew, tucked under a bridge, or a landmark you've walked past a hundred times without really seeing. You need to crack the code in that clue. Work out the location. Melbourne is a big place, and we use all of it. Tokens are hidden across various zones: north, east, bayside, west. This means the hunt spreads out. It's not always in the CBD. So, whether you're in Footscray, Preston, St Kilda, or Box Hill, there's a good chance a hunt will eventually land near you. This encourages you to explore different parts of the city you might not visit otherwise. It rewards local knowledge. And a bit of legwork. Once you have a location, you go there. Physically. Your phone's GPS has to put you within 75 metres of the sticker. You then take a photo of the token exactly where it sits. This picture has to match the real-world location. We verify both your GPS and the photo. There are no exceptions. You can't win from your couch. You have to be standing there. If you're the first to submit a verified find, a 15-minute exclusive window opens for you. You get a skill question. Answer it correctly within that time, and the cash prize is yours. If you get it wrong, a five-minute cooldown period begins, and your 15 minutes keep ticking down. If your window runs out before you answer correctly, the question opens to every member. Then it's a race. This structure means being first to the spot is a huge advantage, but it doesn't guarantee a win. You need to think under pressure.

What Makes a Hub 4 Hunt Different?

We've built Hub 4 to be fair. Very fair. The first version had issues. The same few people kept winning. We fixed that. This rebuild addresses it with a few key features.

Clues That Grow With You

Your clue is unique. Everyone gets the same core information at the same moment. But the wording, the voice, it changes. It's personalised for you by AI. This means nobody gets an information advantage. And you can't just copy someone else's clue word for word and get ahead. It's designed to be for your eyes only. As you get closer to the token, more help unlocks. If you get within 400 metres, a second clue appears. This one describes what you'd see from across the street. Get within 120 metres, and a third clue unlocks. This tells you almost exactly where the token is. You don't buy these clues. You earn them by being there. The city whispers its secrets as you close in.

Skill Leagues and Lasting Rewards

Some people play every week. That's fine. We have skill leagues for that. Consistent winners are promoted to higher divisions. These divisions have harder clues. This keeps the entry division open for newer members. Everyone competes at their own level. It keeps the playing field even. Even after a hunt is won, the token stays where it is. If you find a won token later in the week, photograph it, and pass the location checks, you still earn 50 skill points. This means a walk is never wasted. The city always has something to give you. Scavenge Melbourne. Claim your win.

Things to Do in Melbourne on the Weekend

Melbourne is full of things to do. But sometimes you want something different. Something that pushes you. Something that isn't touristy. Hub 4 offers a unique way to engage with the city. It's an outdoor activity Melbourne adults can really sink their teeth into. Instead of just wandering aimlessly, you have a purpose. You're tracking a target. You're solving a puzzle. You're discovering hidden corners of the city that even lifelong residents might miss. It's a challenge for your brain and your feet. It's a reason to get out and explore. For example, have you ever really looked at the historic plaques and sculptures around the Royal Exhibition Building, a UNESCO World Heritage site Royal Exhibition Building? Or thought about the details tucked away in Fitzroy's back lanes? Hub 4 makes you see the city differently. You might find yourself searching through the gardens of Queen Victoria Market, or along the Yarra River's less-frequented paths. It's a healthy way to spend a Saturday. You're walking. You're thinking. You're competing. It's a mental and physical workout. It gives you a reason to go somewhere you wouldn't otherwise go. And if you're quick and clever, you walk away with cash. The city is rich with these kinds of opportunities. You just need to know where to look. The City of Melbourne offers a wealth of public spaces, from sprawling parks like the Royal Botanic Gardens to tiny urban nooks. We use these spaces. We use the public infrastructure. The city itself becomes the game board. You'll navigate its tram lines, its iconic laneways, and its quiet residential streets. Every corner holds a possibility. Even the details of the Melbourne skyline Melbourne skyline could be relevant to a clue. Hub 4 isn't just another thing to do. It's a commitment. A challenge. It's a reason to sharpen your observational skills and put your knowledge of Melbourne to the test. The next hunt starts on 15 August 2026. This is when the relaunch kicks off. We've rebuilt this from the ground up to ensure it's fair, engaging, and genuinely rewarding. Melbourne is waiting. The next hunt starts 15 August 2026. Join the hunt at hub4.au.
