Kimberley residents and tourists are asked to be on the lookout for the highly invasive weed Praxelis (Praxelis clematidea) after it was found on a 12 Mile property near Broome.

The Department of Primary Industries and Regional Development has been working to eradicate the declared pest from the State, with the Broome infestation on the decline in recent years.

Broome-based biosecurity officer Simon Marwick said after years of hard work, the confirmed sightings of mature, seeding plants at the 12 Mile property was a setback.

“We are working to get on top of this latest infestation as quickly as possible to stop the spread of this highly invasive weed,” Mr Marwick said.

“Although only in the early stages of establishment, these weeds have the potential to seriously impact Australia's environment and agriculture.

“Small infestations can be eradicated if they are detected early, but an ongoing commitment is needed to ensure new infestations do not establish.”

Praxelis is a C2 classified declared pest in the Kimberley, meaning there is a legal requirement for land owners to eradicate this weed.

Praxelis threatens biodiversity, can significantly increase the costs of managing crops and can infest pastoral grasslands and conservation areas.

An herbaceous plant growing up to one metre, the Praxelis stem is covered with coarse segmented hairs, it bears green somewhat sticky leaves, and has a pungent odour when crushed. It has purplish-blue or lilac flowers arranged in flower heads in flat-topped clusters.

Mr Marwick said it was important to report the pest weed to DPIRD and for landowners to not undertake control measures without assistance as it may actually spread the weed.

Anyone reporting a sighting of Praxelis, should contact the department’s Pest and Disease Information Service (PaDIS) on (08) 9368 3080, or email

Reports can also be made by downloading the mypestguide reporter app and by contacting the Broome DPIRD office.
