The Queensland Parks and Wildife Service's booking system has been hacked.
The Queensland environment department says it does not believe financial information has been compromised.
The department says park users should be wary of phishing attempts.
The Queensland Parks and Wildlife Service's booking system has suffered a data breach, with hackers stealing personal user information.
The Department of Environment, Tourism, Science, and Innovation told 612 ABC Brisbane that the third-party provider Bookeasy had been hacked.
Bookeasy had processed camping and vehicle access permits for the National Parks Booking System, storing personal emails, addresses, and phone numbers.
The spokesperson said "at this stage" they did not believe customers' financial information was accessed, as payments are processed through a separate system.
The department spokesperson said park users should remain wary of phishing attempts by hackers impersonating national park staff.
"If you receive an unexpected email, text message or phone call claiming to be from the department and asking you to confirm or provide personal information, do not respond, click on any links, or provide any personal information," the spokesperson said.
"We take the privacy and security of your information extremely seriously and will provide further information to affected customers as soon as we know more."
The spokesperson said any suspicious activity should be reported directly to the Queensland Parks and Wildlife Service…
