This presentation includes a detailed documentary video. Desert Channels Queensland (DCQ) collaborated in pioneering satellite weed mapping to build a regional picture of the prickly acacia problem; researched and developed drone and other control methods; and developed a social media based field mapping system. Weed PACTs bring together groups of adjoining properties under five-year plans that divide the labour and cost. DCQ handles the toughest infestations and the landholders deal with the balance. This approach fostered a strengthening commitment from graziers to stick with the plans. The combination of plans and new control techniques matched to weed density and land type, dramatically reduced costs to graziers and funding agencies. The benefits now far outweigh the costs of weed control. DCQ tapped into changing legislation to have an Area Management Plan approved, and negotiated a special Australian Pesticides and Veterinary Medicines Authority permit. These allow them to efficiently tackle the critical, ultra-dense infestations along drainage depressions. The Weed PACT initiative attacks infestations along upper reaches of Lake Eyre Basin rivers, delivering a huge public benefit both inside the infested areas and in the productive channel country downstream. DCQ has used YouTube news stories and field days to share the vision and successes of Weed PACTs, fuelling the enthusiasm of graziers, researchers, and governments to tackle what was once assumed an insurmountable problem for grazing businesses and for the future of the Lake Eyre Basin rivers.

MANY HANDS MAKE LIGHT(ER) WORK OF WEEDS AND PESTS IN THE FAR NORTH Travis Sydes Far North Queensland Regional Organisation of Councils [email protected] SUMMARY In 2009 local governments of Far North Queensland began development of an MOU outlining a collaborative approach for delivering regional resource sharing in joint operations referred to as taskforces. The agreement was specific to the management of natural assets in both disaster response and regionally significant issues like invasive species. The concept borrowed from and built on operational taskforces from programs like the Siam weed and Four Tropical Weeds eradication programs and looked to even
