Travellers planning holidays in Western Australia’s Kimberley region have been targeted by phishing scams following a data breach involving RMS, a third-party accommodation booking provider.

The incident has raised concerns because the fraudulent messages contained genuine information about customers’ hotel reservations, making them more difficult to identify as scams.

One affected traveller, Sydney resident Cameron Craig, received a Whats App message about his upcoming accommodation booking at Cable Beach Club in Broome. The message included his full name and the correct dates of his planned stay.

It asked him to provide payment details through a link and warned that his reservation could be cancelled if he did not complete the requested payment.

Although Craig considered himself familiar with online scams, the accurate booking information made the message appear genuine. He clicked the link and entered some credit card information, but the session timed out.

He later noticed warning signs, including the international phone number used to send the message and a reservation code that did not match his actual booking. He alerted the resort, which subsequently notified guests about the suspicious communications.

Other accommodation businesses in the Kimberley have also received reports from customers. Kimberley Accommodation Group, which uses RMS Cloud for its reservation services, said guests had reported messages asking them to confirm card details or make payments using information connected to their bookings.

The company said it could not yet confirm how many customers had been affected or whether guests had suffered financial losses.

RMS confirmed that unauthorised activity within its systems had been contained on 2 November. The company said investigations were continuing to establish the full extent and impact of the incident. Its chief executive also confirmed that credit card and payment details were not involved in the reported breach.

Cybersecurity experts have warned that criminals are increasingly using personal information to make fraudulent messages more believable. Unlike traditional phishing attempts containing obvious spelling mistakes or generic requests, these messages can use real booking information to create a sense of trust and urgency.

The incident may also affect other accommodation providers and businesses that rely on third-party reservation platforms, including smaller hotels, bed and breakfasts and temporary accommodation services.

Travellers are being advised not to click unexpected payment links or provide financial details through messages claiming to relate to hotel reservations. Customers should contact their accommodation provider directly using contact information from its official website or booking confirmation.
