Wetlands Condition
Tracking the condition of wetlands across the Great Barrier Reef catchment
Healthy waterways underpin our lifestyles and livelihoods. When waterways thrive, so do we.
Together, Aussies eat more than 5 million bananas every day. And 90 per cent of them are grown in the Wet Tropics. It’s intensive land use in a high rainfall region. So it’s great to see farmers working hard to reduce topsoil, pesticide and fertiliser run-off.
When Mena Creek banana farmer Sukhpal Singh Chahal plans for a new block of bananas it’s no longer simply about straight rows and planting into the land as it comes. These days he’s also thinking about soil types, the natural flow of water through the farm and how he’ll contour his paddocks.
Sukhpal is one of 30 growers working with the Australian Banana Growers’ Council’s Best Practice Management Team to improve crops through better use of fertiliser and, in doing so, also improve the quality of water running off their land into creeks and rivers.
Soil and leaf sampling, mapping and soil health workshops are part of the project to create a comprehensive farm nutrient management plan. And through grants that he’s been matching dollar for dollar, he has upgraded farm equipment to change fertilising and mulching methods, and has contoured the farm’s steepest slopes.
“Now we use less pesticides because we’re using a side-thrower slasher between the banana rows, so we’ve got more mulch around plants to suppress weeds naturally,’’ he says. “And when we cut the trees, we put the leaves and stems inside the rows.
“We’re matching fertiliser use to the crop’s needs better and trying to use less. If you don’t do that right it affects production, so being part of this has been very helpful.”
Sukhpal is also one of 13 banana growers working on a water-sampling project in the Utchee Creek area with scientists from TropWATER and Terrain NRM and extension officers from the banana growers’ council. Water is being monitored for sediments, nutrients and pesticides in rainforest above the farmland, in the creek near each farm and downstream from the farms.
“The sampling happens once a month and from time to time we get information,’’ he says.
“After the data we’re always looking at how we can improve the water leaving our farm. We can see what’s going through the water now and it helps us with the bigger picture. Before we’d kill grass along the creek banks. Now we’re leaving it. We know it helps to catch the soil particles.”
Molly Blake from the Australian Banana Growers’ Council says practices are changing across the industry and one example is more ground cover on banana farms.
“Grassed inter-rows are keeping soil on the land by minimising the impact of our high rainfall and increasing the take-up of soil. They’re also helping to improve soil biology and soil health.
Banana growers across all growing districts are working with ABGC to improve their knowledge and farming practice to limit the impact of the farm on their local waterways and the reef. They know that it is important to use sustainable practices to grow beautiful bananas in a beautiful part of the world.”
The Australian Banana Growers’ Council’s Best Management Practices Project is funded through the Queensland Government’s Queensland Reef Water Quality Program. Development of nutrient management plans has been funded by the partnership between the Australian Government’s Reef Trust and the Great Barrier Reef Foundation through the Cassowary Coast Reef Smart Farming Project. The water monitoring program is funded by the Local Scale Water Quality Monitoring Program under the Queensland Reef Water Quality Program and the partnership between the Australian Government’s Reef Trust and the Great Barrier Reef Foundation.

Martine joined the Wet Tropics Waterways team as a Science Technical Officer in early 2024 and is keen to apply her experience in statistical programming and database development for the Report Card.
She is an environmental scientist and ecologist and has worked on water quality and aquatic ecology projects as a consultant and in private industry for over 20 years.
Martine has many hobbies and is currently dabbling in horticulture.
With a degree in marine biology and zoology from JCU, Phil has had a diverse career covering research in fisheries biology, 15 years in reef tourism and 13 years with GBRMPA delivering engagement and partnerships programs. Since 2019 he has been self-employed and operates as a consultant to a range of stakeholders on waterway related programs.
He is a keen fisherman.
James joined Wet Tropics Waterways as Executive Officer in 2021 and is passionate about working with stakeholders to communicate the value of our unique waterways. His role involves facilitating and coordinating our partnership program, growing our network and investment into the report card program, and science communication. James oversaw the 2022 Innovations in Waterway Health Forum, and hosted season four of the Reef and Rivers podcast.
James is an ecologist and has previously worked on wetland management in the Murray Darling basin, fish passage in Mackay, and aquatic research in the Wet Tropics.
Outside of work you’ll find him in a local waterway with a mask and snorkel, or hiking or biking around our beautiful region.
Richard has been the Science Technical Officer for Wet Tropics Waterways since 2016. His role involves producing the annual results for the waterway health assessment of the wet tropics region using data from a wide range of sources, to present as scores and grades, as well as developing new indicators to address knowledge and monitoring gaps. He works in collaboration with technical staff at other regional report cards.
Richard has a background in freshwater ecology research projects and environmental assessments with CSIRO, University of Queensland, Queensland Government and as a consultant. For a long time he’s been interested in freshwater aquaculture and continues this interest through farming freshwater crayfish, alongside other farming activities.
