Two people who moored their yacht in waters off K'gari (Fraser Island) are facing possible fines after a woman exercised two domestic dogs on the beach.
Ranger in Charge Linda Behrendorff said domestic dogs have been banned on the island by the Queensland Parks and Wildlife Service since 1991.
"In 2011, the Fraser Coast Regional Council supported us by banning domestic dogs in residential areas to help protect the population of wongari," Ms Behrendorff said.
"Domestic dogs are incompatible with the natural values of K'gari and the wongari on K'gari are among the purest strain in Australia.
"Rangers from the Queensland Parks and Wildlife Service and the Butchulla Aboriginal Corporation take a zero-tolerance approach to people who break the rules.
"Although the woman kept those dogs on a lead while they were exercising on the beach, she will receive a fine when she can be identified.
"Rangers have reviewed photos of the boat, but cannot find a registration, and we're asking for public assistance to help identify the people on the boat.
"Domestic dogs carry diseases or viruses, including heartworm or Parvo virus that could become an issue if it was passed from a domestic dog to the wongari population.
"The presence of domestic dogs on the island can also cause stress for wongari and could result in a negative interaction between the wongari, dogs or their owners.
"If the domestic dogs broke off the lead, they could become lost while exploring, which might leave them vulnerable to the wongari.
Ms Behrendorff said certified support dogs are the only dogs permitted in national parks, and they must wear an identifying coat or harness, the approved badge or tag, be kept on a lead and owners must have the authorised paperwork.
"Domesticated pets do not belong in national parks, and people need to check our website before planning their trips," she said.
