An Uber driver has been banned from picking up passengers at Perth Airport after the driver defecated in one of the rideshare holding bays.

Radio 6PR's Morning host Gareth Parker obtained an email from Uber to the driver which claimed their access to the airport would be "revoked immediately" because they were spotted by a Perth Airport staffer defecating near Horrie Miller Drive within the Terminal One and Two precincts on Tuesday morning.

WAtoday understands it's not the first time such an incident has occurred.

"This breached the above Rideshare Driver Access Terms and Conditions, as you have behaved in a manner deemed antisocial and offensive," the letter read.
