Wandering down the unlit corridors of a six-storey building behind the Royal Hill casino, each door opens onto a different world.
In one there is a perfect replica of a Vietnamese bank. In another, you're in an Australian police station. A Chinese police officer's shirt hangs in one corner.
Motivational messages have been painted on the walls. "Money Coming From Everywhere", read the Chinese characters on one sign. Discarded fake hundred dollar bills are lying all over the floor.
This was a massive scam compound, just inside Cambodia in a border town called O Smach. Thousands of people from different countries worked here, under a harsh regime which strictly regimented their lives, defrauding thousands of others across the world of their savings.
In December Royal Hill was bombed by the Thai air force during the brief border war between the two countries – the Thais say Cambodian drones were being launched from the casino. The workers fled, leaving behind uneaten bowls of noodles, half-drunk cans of coke and a pungent smell.
