Motorbike Rental Damage Scam
Rental shops on Koh Tao take a cash deposit or passport, then inspect bikes meticulously on return and cite pre-existing scratches as new damage, refusing to refund the deposit.
📍Motorbike rental shops along the main Mae Haad Road in Mae Haad village, Sairee Beach Road, and at the Koh Tao pier arrival area, Koh Tao, Surat Thani province, Thailand
How to avoid: Never surrender your passport as collateral — it is illegal in Thailand. Photograph every millimeter of the bike before riding and send photos to yourself with a timestamp.

How it works
Rental shops on Koh Tao take a cash deposit or passport, then inspect bikes meticulously on return and cite pre-existing scratches as new damage, refusing to refund the deposit.
How it works
Budget dive shops collect full payment for PADI or SSI courses then deliver shortened sessions, skip required dives, use poorly maintained equipment, or disappear with the money entirely.
How it works
Drinks spiked with sedatives are reported in beach bars around Sairee Beach. Victims are robbed while unconscious. Some reports involve bucket cocktails purchased from beach vendors.
How it works
Unregistered or illegal diving shops operate near the main jetty areas, offering cheap certification courses with instructors lacking proper credentials. Some rush training, skip safety protocols, or issue fake PADI cards that are worthless outside Thailand and dangerous for actual diving.
How it works
After altercations or drug-related incidents near the bars of Sairee Beach, tourists are sometimes detained by local police or "undercover officers" and pressured into paying on-the-spot fines to avoid formal arrest. The amounts demanded are well above any official fine and are kept by the officers involved rather than processed through official channels. Travellers with no knowledge of local law are particularly vulnerable to inflated settlements.
How it works
Boat taxis between the ferry pier and resorts, and shared songthaews on the island, charge tourists 3–5x the local rate with no posted prices and aggressive haggling pressure.
How it works
Friendly locals near the ferry pier claim popular snorkeling spots or viewpoints are "temporarily closed" and offer to take tourists to alternative destinations where they earn commission.
How it works
On and around Sairee Beach in Koh Tao, some smaller restaurants catering to divers add items to bills between the time of ordering and the time of paying. Extra drinks, side dishes, or inflated quantities appear on the final receipt. Because many divers are tired after a day underwater, they are less likely to scrutinise bills carefully, and some staff exploit this.
How it works
Touts operating near the Mae Haad Pier and along Sairee Beach approach newly arrived travellers with offers of cheap bungalows and guesthouses that are "fully booked online." They collect a cash deposit or full payment upfront, then either take you to an inferior property or disappear entirely. The "guesthouses" shown in photos often do not exist or bear no resemblance to the actual rooms provided.
How it works
Money changers at the main ferry jetty offer rates far worse than banks or legitimate exchange offices, sometimes showing a good rate verbally then applying hidden fees or delivering short amounts of baht after the transaction.
