You're required to wear a mask on all Australian domestic flights.
It is requirement by Federal, State and Territory governments to wear masks at airports and inflight. Your face mask needs to cover your mouth and nose, fit securely and must be worn unless you're under 12 years of age or have a medical condition. A scarf or bandana is not considered a face mask.
When travelling within Australia, you'll need to wear your mask as soon as you enter the airport, and also inflight.
Ensure you’re aware of any government requirements that apply at your destination, including wearing face masks and coverings.
