Dunn Aviation is based in Ballidu about two hours drive north east of Perth, in the heart of the wheat belt. For the application of chemical and fertiliser to crops we cover a large area approximately 200-300 km's from our Ballidu base. However, for firebombing, oil spill control and large scale government or corporation work, we have the ability to cover a much larger area. For detailed information please contact us, we are more than happy to discuss options to suit your needs.
