A Melbourne Treasure Hunt Game With A Cash Prize

There's money hidden in Melbourne. Not in a bank vault, not under a mattress. It's out there, stuck to something, waiting for you to find it. Hub 4 is a weekly treasure hunt played on the streets of Melbourne. Solve the clue, track down a hidden sticker, and the cash prize is yours. It's a game of skill, a reason to walk the city, and a chance to prove you know Melbourne better than anyone.

How a Melbourne Treasure Hunt Game Works

Each week, we hide a physical Hub 4 sticker somewhere in Melbourne. It's not in the open. You won't just stumble on it. Your job is to follow the clues, pinpoint the location, and be the first to verify your find. It breaks down into three simple steps.

Get your clue

Every week, a new clue lands in your membership portal. This isn't a vague riddle. It's specific. It points to a landmark, a forgotten alley, or a corner of the city you might have walked past a hundred times without really seeing. You start with the first clue, and that's your entry into the hunt.

The clues are personalised. Everyone gets the same information at the same moment. But the wording, the voice, it changes just for you. Nobody gets an advantage, and there's nothing to copy off anyone else. You're on your own, and that's the point.

Find the token

Once you think you've cracked the clue, you go. You head out into Melbourne. Maybe it's near Flinders Street Station, or deep in Fitzroy, or even out in Footscray. You physically navigate the city. When you get there, you're looking for a small Hub 4 sticker, no bigger than a coaster. It's hidden, not just placed. It might be behind a downpipe, under a bench, or tucked away in a recess. Your phone's GPS needs to put you within 75 metres of it. Then you snap a photo of the sticker, exactly where it sits, and you submit it. That's your claim.

Location is how we know it's real. You have to be there. GPS must be on. Your photo must match the actual spot. No exceptions. Nobody wins from their couch. For more on how this works, check out Melbourne's serious scavenger hunt.

Winning the Cash Prize

Finding the token is a major step, but it doesn't mean you've won the money. The cash prize comes down to skill, and it pays out within 48 hours of a verified win. There's no lottery here, no random draw. It's a straight contest.

Claiming your window

The moment your photo and GPS verify your find, a 15-minute exclusive window opens. It's just for you. During this time, nobody else can claim that token. You have 15 minutes to answer a skill question. Get it right, and the prize is yours. It's a test of quick thinking under pressure, not just legwork.

If you get the question wrong, a five-minute cooldown period begins. Your 15-minute clock keeps ticking down. If your window runs out before you get the question right, the opportunity opens to every other member. Then the race is truly on for anyone who has found the token and is still within their own claim window. Being first to the sticker gives you a real advantage, but it never guarantees the win. The prize goes to whoever earns it.

What if someone else wins?

The hunt is competitive, and only one person wins the cash prize each week. But your walk isn't wasted if someone else gets there first. The sticker stays stuck down. Find it later in the week, photograph it where it sits, and you still earn 50 skill points. You can spend points on extra clues in future hunts. It keeps the city worth exploring.

Not Just Another Scavenger Hunt Melbourne

Hub 4 isn't a tourist gimmick. It's a genuine challenge, one of the more unique things to do in Melbourne on the weekend. We built it for people who know the city, who like to walk its odd corners. The game rewards local knowledge and persistence. This isn't about silly hats or tourist traps. It's about Melbourne, the hunt, and the cash.

Our roots go back. Hub 4 ran before, and it had a problem: the same few people kept winning. We rebuilt it from the ground up to fix that. The new system is designed for fairness and skill. It starts its first hunt on 15 August 2026.

Clues that change for you

The AI personalises your clue. It’s the same information everyone else gets, but the wording is unique. This means you can't just copy someone else's clue word-for-word. Everyone starts from the same information, but you decipher it your way. It levels the playing field, making sure every win is earned through individual effort.

Closer means clearer

As you get closer to the hidden token, more help unlocks. Get within 400 metres, and a second clue appears. It describes what you'd see from across the street. Walk within 120 metres, and a third clue tells you almost exactly where the sticker is. You unlock these clues by being physically present. It means the legwork pays off, literally. The more ground you cover, the more information you get. It’s a rewarding outdoor activity for adults in Melbourne, making the city itself part of the puzzle.

Hub 4 runs across zones spanning the whole city – north, east, bayside, west. This ensures wins spread out and don't just favour those living closest to the CBD. You might be exploring the historic laneways of the CBD one week, or the quiet streets of Williamstown the next. It encourages you to find new weekend activities Melbourne that aren't the usual tourist fare, like exploring the vibrant street art of Fitzroy or the historical buildings around the City of Melbourne.
