About Us


For over 130 years Comet Windmills have successfully pumped water in the Australian Outback. They are legendary for sensitivity, simplicity and great strength. The Comet Mill is low in maintenance, highly efficient and a long term sustainable investment.


Your initial cost will be your last with a Comet Mill and they require a drop of oil perhaps once a year for maintenance. Being highly cost effective they are comparable in prices to any other water pumping plant on the market today with a higher standard of quality that has come to be expected. You can expect many years without replacing any major spare parts.
