Prohibited invasive plants
Everyone is obligated to take all reasonable and practical steps to minimise the risks associated with invasive plants under their control. This is called a general biosecurity obligation (GBO).
Prohibited invasive plants are not present in Queensland and:
- seriously threaten Queensland's primary industries, natural environment, livestock, human health and people's livelihoods
- must be reported to Biosecurity Queensland within 24 hours of the sighting. A person reporting the prohibited invasive plants must take all reasonable and practical steps to minimise the risk of it spreading or escaping until they receive advice from an authorised officer.
Many prohibited invasive plants have related species that are classified as restricted invasive plants. You should view both the prohibited and the restricted invasive plants pages to understand what your responsibilities are.
You can find detailed information on individual invasive plants below, and a summary of the restrictions and a list of restricted invasive plants in the Prohibited invasive plants of Queensland fact sheet (PDF, 710KB).
