Diatomaceous Earth Online™ supplies premium-grade Australian diatomite (also known as natural amorphous silica). Sourced directly from one of the world’s largest known and highest quality deposits*, our freshwater DE is taken from the ancient freshwater lakes of Mount Garnet, Far North Queensland. We process the Diatomaceous Earth directly from the mine, enabling us to ship throughout Australia and internationally, in quantities from as little as 1kg, to many tonnes, at very competitive prices.
Our diatomaceous earth is Food Grade, 100% natural and chemical free, and has been certified by the Queensland Government as containing an undetectable amount of crystalline silica (less than 1%) . It has no additives and has not been subject to any manufacturing process other than crushing and bagging. It is only sun-dried and has not been subject to any artificial heat treatment – making it safe to use in the home, garden and on the farm.
Whether you are a large-scale agricultural producer, run livestock, a professional horticulturist, a breeder, a home gardener, or a pet owner, you will find many uses for Diatomaceous Earth.
