Declared weeds prohibited to trade
This list provides information on plant species that are banned from trade (buying and selling) by State and Territory under each respective jurisdictional legislation. Each jurisdiction has different legislation, and some will have exceptions for different species and genera. These conditions can be found on each jurisdictional declared plant species webpage available here.
Declared weeds are plants acknowledged as invasive/noxious/pest under state and territory legislation. Typically, legal control measures are applied to these declared plants.
In some States and Territories there are also general biosecurity obligations on other pest plants and there are recommended measures that people in that jurisdiction should also follow.
Some plants species should not be sold, but these are not listed on the declared plants from trade list and instead alternative plant species are promoted through the Gardening Responsibly scheme. Illicit species and controlled substances are also a different matter and are dealt with under relevant legislation or require specific licences.
Although this list is as comprehensive as possible, it is a guide only. Please make sure you check your relevant State and Territory website for updates in legislation regarding trade of plant species. Start your search in our Lists section.
This list is for trade only: restrictions on movement may apply to these plant species, however these specific prescriptive movement controls are not part of this guide.
The ‘Prohibited to Trade’ tab is a full list of plant species and genera. Jurisdictions with whole genera declared will include specific species if listed by other states. Be sure to check a plant’s taxonomic synonyms against this list. Jurisdictions are not in complete agreement on accepted taxonomic names. Some synonyms are provided if in use by jurisdictions.
The individual tabs for each State and Territory have a more extensive list and will itemise any exceptions to that plant species.
