All passengers must be screened before they enter a secure area of an Australian airport terminal and boarding a flight.
The Australian Government understands that some cultures incorporate elements of clothing into their religious observance. Religious or cultural headwear or items of outer clothing may remain for primary screening. However if you cannot be cleared, you may undergo further screening which may involve the removal and searching of your headwear or items of outer clothing.
You can request that this additional screening take place in a private room and by a screening officer of the same gender.
Carrying religious items
Some religious items may meet the definition of a prohibited item under Australian law. If in doubt, pack these items in your checked baggage or make other arrangements to transfer these items to your destination.
