Australian macadamia industry celebrates its champions on National Agriculture Day (2023)

Australia’s best macadamia growers have been honoured in the industry’s Awards of Excellence, announced the Australian Macadamia Society (AMS) today.

Experienced macadamia growers Jason and Fiona Klotz from Red Rock Macadamias in Bundaberg have taken out the Grower of the Year (large farm) award, which recognises consistent high production over the last five years. Their 80ha orchard achieved 1.69 tonne saleable kernel per hectare (1.69 t/ha SK) average over the last five seasons. Jason and Fiona, who have been in the macadamia industry since 2006, have taken out this prestigious award an impressive three times over the last six seasons. Jason is a fifth-generation farmer, and the Klotz family have been farming on the home farm for 150 years. Son Sam is now also part of the macadamia business.

Winner of the Grower of the Year (small farm) award are Gary and Julie Davis from the Glass House Mountains region whose 13.8hectare orchard ‘Glendamia Park’, achieved an average of 1.91 tonne saleable kernel per hectare (1.91 t/ha SK) over five seasons. Originally from broadacre cropping, Gary (a third-generation farmer) and Julie established their orchard, located just 2.5km from the coastline, 25 years ago and their son Mitchell joined the operation in 2015. The family also took out the Grower of the Year award in 2019. 

The AMS also announced the regional award winners for the 2022 season (listed below) across the macadamia growing regions of Central QLD, Gympie QLD, Glass House Mountains QLD, Northern Rivers NSW and Mid North Coast NSW. 

AMS CEO Clare Hamilton-Bate congratulated all Awards of Excellence recipients whose attention to detail, on-farm innovation, collaboration and focus on long-term orchard health was nothing short of exceptional.

“We are an industry powered by the collaboration and innovative thinking of our people. Our award winners are a great example of this and understand what it takes to shine in the unpredictable and sometimes unrewarding world of farming.”

Ms Hamilton-Bate said Australia, the original home of macadamias, is a recognised global market leader that enjoys an enviable reputation for its high-quality macadamia nuts and world’s best production practices. 

“We have our growers to thank for this reputation. Our growers and our industry are committed to the pursuit of excellence, from practices adopted on farm, to post-harvest handling and the premium quality of the end product.”
