Cairns, Port Douglas and the Wet Tropics: rainforest-catchment tanks, Barron River town supply, Tablelands basalt bores, and a cyclone-and-flood context that resets tank chemistry every wet season.
Cairns draws from Behana Gorge and Copperlode Falls Dam. Wet-season turbidity spikes are a recurring seasonal issue managed at the plant.
Dominant north of the Daintree and on rural Tablelands blocks. High wet-season rainfall means fast turnover but heavy leaf-litter and wildlife load — annual testing is a genuine must.
Atherton Tablelands bores tap volcanic basalt — hardness, iron and manganese dominate. Some deep bores show elevated fluoride.
Stock and irrigation across the Tablelands and Cairns hinterland. Blue-green algae watch during warm dry stretches.

Cairns, Edmonton, Trinity Beach, Palm Cove. Cairns Regional Council supply from the Behana Gorge and Copperlode Falls dams; tank-supplemented eco-builds along the northern beaches.

Port Douglas, Mossman, Daintree, Cape Tribulation. Off-grid tank properties dominate north of the Daintree River — annual testing plus post-cyclone testing recommended.

Atherton, Malanda, Yungaburra, Ravenshoe. Cool-climate basalt-plateau bores and Tablelands Regional Council supply; rainwater tanks on grazing and cropping blocks.
Physical, chemical, and microbial parameters analysed to ADWG.
