Fly season in Australia: what you need to know before summer

Summer in Australia means longer days, barbecues, beach trips - and more flies than you can swat a thong at. If you’ve ever found yourself deep in conversation with a mate while simultaneously waving at your own face, congratulations: you’ve survived another fly season in Australia.

But why does it happen? And how can you prepare before the swarms descend? Here’s your quick guide to fly season - and how to enjoy summer without becoming a bug buffet.

When is fly season in Australia?

The short answer: spring through summer, especially October to March, depending on where you are. But here’s the breakdown:

• Southern states (like VIC, SA, southern WA): peak season is November to February.

• Northern regions (like QLD, NT, northern WA): flies are year-round but get worse during the wet and just after.

• Rural and regional areas tend to have heavier fly loads than urban centres, thanks to farming, livestock and wide open spaces.

Bonus tip: Flies love heat, moisture and anything even remotely food-adjacent. So your perfectly curated charcuterie board? Party central.

Why are Aussie flies so relentless?

Not all flies are created equal. Australia’s most infamous airborne pest is the bush fly - smaller than a housefly, and much more persistent. They don’t bite, but they land constantly on your face, looking for moisture (sweat, tears, saliva - you know, the glamorous stuff).

They’ve evolved to keep bugging you until you physically brush them away. That’s why Aussies develop the “Aussie salute” — the constant hand wave you do when talking outdoors.

How to prepare for fly season

Before the swarms kick in, stock up on a few essentials to keep your summer bug-free(ish):

1. Get a fly net - and actually wear it

A good-quality fly net is the easiest, chemical-free way to block flies from your face. Our Fitness Fly Net and Fashion Fly Net are both lightweight, breathable, and - dare we say - they look way better than the cheapies you get from the roadhouse. 

2. Cover food quickly

Use mesh domes or throw a tea towel over your nibbles board. Don’t give flies a buffet.

3. Keep bins sealed and clean

Outside and inside. Flies love to lay eggs in a wheelie bin 🤮

4. Embrace the eucalyptus

Flies hate the scent of eucalyptus and lemon myrtle. Try a natural spray or diffuser outdoors.
