The 22nd Australasian Weeds Conference was to be held in late 2020, but this had to be postponed by a year because of Covid-19. It will now be held in Adelaide on 22-29 September 2022.
Presentations from past conferences are published as the Proceedings of the Australasian Weeds Conference series and are available for download here.
