Dingoes were once common on the island, but are now decreasing. They are some of the last remaining pure dingoes in Eastern Australia and to prevent cross-breeding, dogs are not allowed on the island. There was no recorded history of dingoes attacking humans on Fraser Island up until 1995. In April 2001, a boy wandered away from his family and was discovered dead, with indications of a dingo attack. Forty dingoes were killed by authorities as a result of the incident. In 2004, a dingo entered a hotel room on the island where a baby was lying on a bed. It was chased off before any incident occurred. The relationship between dingo attacks on humans on Fraser Island has been documented on National Geographic. Caution with dingoes when on Fraser Island is mandatory for all people on the island. Feeding or attracting the attention of dingoes remains illegal. The remaining number of dingoes on the island is estimated to be 120 to 150 as of January 2008 and sightings are becoming rarer.
