Even the experts reckon the flies are unpleasant at the moment.
Department of Primary Industries' entomologist Joanne Holloway reckons the flies seem to be "more annoying than usual".
Dr Holloway suspects that the dry, windy conditions could have something to do with it.
She said the dry weather means there is more animal dung lying on the ground.
"We've had a lot of wind, and that brings the flies in," Dr Holloway said.
"They're coming in from the warmer areas. The temperatures have helped them breed."
Dr Holloway has also noticed that the flies this year seem to be a little smaller.
"When they are smaller, they tend to get more anxious. They need more protein. Annoyingly, they are going to try to get that protein from us, or at least from the moisture on our skin. They're taking liquid up, like a sponge. They're mopping it up," Dr Holloway said.
