Use by the 15th of October, it doesn't appear to have a minimum spend. Came from a survey, hopefully works for others. If you did get the survey email then this is the code at the end of it.
It should also work on pick up orders, to avoid delivery and service fees.
A promotion for $5 off your next order (fees apply). Maximum of $5 off order value applies. $5 off does not apply to fees. Valid for use on up to 1 order only. Delivery Fee applies (excluding Pickup orders). Service Fee applies to orders delivered by Uber Eats and is based on order value (before promotion or discount). Other fees may apply. Any remaining value is forfeited if order value is below $5. Amount of up to $5 will be applied as a promotion at checkout. Valid only in Australia where Uber Eats is available. To redeem this Offer, open the Uber Eats app, apply the promo code to your account, add 1 or more items to your cart, check the Offer has been applied at checkout, and then place your order.
Waiting on a new PMAU code
