Cocos palm

Native to Brazil, the Cocos or queen palm is a fast-growing, long-lived, resilient palm traditionally grown in many Queensland gardens. It is a prolific seeder, and seed is spread by bats into gardens and bushland. Cocos palm can invade riparian areas and dry eucalypt forest.

Cocos palm is not a prohibited or restricted invasive plant under the Biosecurity Act 2014.

Legal requirements

  • Cocos palm is not a prohibited or restricted invasive plant under the Biosecurity Act 2014. However, by law, everyone has a general biosecurity obligation (GBO) to take reasonable and practical steps to minimise the risks associated with invasive plants under their control.
  • Local governments must have a biosecurity plan that covers invasive plants in their area. This plan may include actions to be taken on Cocos palm. Some of these actions may be required under local laws. Contact your local government for more information.
