Gabe Brown - regenerative farmer, North Dakota, USA


Gabe is a pioneer of the current soil health movement that focusses on regenerating our resources. His diversified 5,000 acre farm and ranch near Bismarck, North Dakota, USA focuses on farming and ranching in nature’s image with holistic integration of his grazing and no-till cropping system. A diversity of cash crops and multi-species cover crops, and all-natural, grass-fed beef, poultry and sheep has regenerated the natural resources on the ranch without the use of synthetic fertilizers, pesticides or fungicides. View Gabe's opening presentation here

John Attard - sugar cane farmer, Mackay, Queensland 

John Attard shared the story of how he and his brother Michael have reduced inorganic nitrogen to zero in their sugar production through the application of bio-fertilisers made on the farm. They have created a range of different inputs and modified equipment to apply them. Combined with retaining crop residues and monitoring mineral levels closely, they are showing promising yield results, and have saved considerably on pumping costs. Here's John's story.

Marcus Bulstrode - Queensland Department of Agriculture and Fisheries, South Johnstone


Marcus works to improve on-farm weed control by encouraging natural regeneration of riparian zones in the Wet Tropics region where the landscape is deeply incised with many rivers and creeks amongst farm land. “By providing conditions [on farms] suitable for natural regeneration, we can re-establish ecosystem functions and develop greater resilience to disturbance and reduce the need for on-farm weed control.” Marcus has also pioneered the use of drones in weed detection and management. He has helped a local farmer to use drone technology to minimise herbicide use in sugar cane.

Alan Coates - Coates Horticulture/TAFE instructor, Wollongbar, NSW

Ian and Di Haggerty - sheep and wheat, Wyalkatchem, WA


Join Ian and Dianne for their story of diversified pasture management. With son James, they run a holistic and integrated program of cropping and grazing over 8,000ha. The program is underpinned by their shared deep commitment to the regeneration of the fertility of the marginal soils of their area. This is achieved through using biological fertilisers, zero tillage and the consequent growth of healthy cereal plants to deliver high tonnages of premium grain per hectare. The healthy ground cover of the cropping and pasture is also key to maintaining high soil moisture levels and ensuring weed control.

Dave is also a NSW TAFE instructor. Dave has spent considerable time in the Wet Tropics and brought his expertise to a composting session, pre-conference tour down the coast and a workshop on understanding your soil.

Dr Vic Galea - Associate Professor in Plant Pathology, University of Queensland

Vic Galea specialises in researching beneficial fungi and diseases of vegetables, fruit, field crops and native plants. His team has developed Australia’s first ‘home-grown’ commercial bio-herbicide, utilising native fungi, that promises to be a sustainable and long-term solution for invasive woody weeds such as parkinsonia, prickly acacia, mimosa and athel pine.

Jo Doolan - organic dairy farmer, Kyabram, Victoria

When Simon and Jo Doolan moved onto their farm near Kyabram, Northern Victoria with their two young children in 2010, it was the realisation of a long held ambition to farm the land first operated by Simon's grandfather in the early 40's. Jo's work in natural resource management and Simon's interest in the environment led them to the decision to farm organically. Their ambition is not to develop a big farm, but a sustainable farm. They have fenced off rare remnant greybox and have plans to create a natural vegetation corridor through their land.

Michael Rocca - farmer and biochar manufacturer, Mareeba, Queensland


Michael Rocca is building his third “prototype” biochar machine after trialling biochar on his cane, peanuts and maize crops for the last five years with great results.  “It has proven to be a highly effective addition to my soil for both increasing yields and stabilising nitrogen. Its wider use has been limited by both supply and cost, so I thought I’d make my own.”

His latest machine will allow him to produce 700kg of biochar per hour. We enjoyed hear from Michael and Dr Lukas van Zwieten.



Don Murray - Nature's Haven, organic producer, Qld and NSW


Don has a passion for agriculture, particularly food production. Tertiary qualifications in agriculture gave him an excellent grounding and experience for establishing Nature’s Haven in 2002.

Don has extensive experience with a wide range of vegetable crops and as a regional agronomist and spoke about the value and challenges of marketing organic vegetables.



Barrie Mackay - Mackays, Tully, Qld


Mackays grows bananas, sugar cane, papaya and beef cattle in the wet tropics. Barrie works closely with his advisors to implement sustainable integrated crop management practices on a large scale. Their soil health program has completely removed synthetic phosphorus inputs and dramatically reduced fungicide usage. They have also successfully introduced integrated pest management (IPM) into their system using a predatory mite, Neoseiulus californicus, for control of spider mite.

Bill and Rhonda Daly - sheep and cropping, 'MiIgadara', Young, NSW


Fourth generation farmers Bill and Rhonda Daly saw that their family farm’s soils were becoming lifeless despite ‘good district practices’. They looked for solutions to restore soil balance and return life to the land. Bill and Rhonda now use ‘Milgadara’ as a model farm to demonstrate the benefits of the biological/humus farming approach. Rhonda is widely respected for her agronomic knowledge of soil and plant dynamics, and assists farmers globally to return their soil to a living ecosystem.

Barry O'Sullivan - holistic management grazier, Glenalpine Station, Collinsville, QLD


Over two decades the O’Sullivans have dedicated themselves to continual personal and business improvement on their 23,700 ha breeder property. With NQ Dry Tropics’ support, they recently used holistic management principles to fix a severely eroded black soil gully. Barry confined a mob of 1200 head of cattle for several nights at the head of the erosion site, which has resulted in a remarkable biological carpeting allowing natural regeneration of pasture and reshaping of the gully.
