Edit: try WELCOMEAUS to see if you're eligible for $30
$20 off code for new UberEats accounts, can't find existing codes in Ozb that are of this value. Referral is $10-$15 so if you don't have a friend's referral this code pays more at $20.
Can also signup for a free 2-week trial of Uber Pass (to save on delivery fee approx $5) or you might want to wait until there is a new Uber Pass offer
For the adventurous, there is an additional US$15 off for new UberEats user from Cashrewards but your cashback possibly/likely will get declined as it says no codes allowed unless listed. If you have an ANZ card, CR offers US$20 for CR Max so use that deal if you satisfy both conditions - new acc and pay with an ANZ card you pre-registered in Cashrewards site.
US$15 (crewa's offer) is about AUD 20.69 but you have to wait for approval etc, and if your transaction didn't track then 🤷
The requirements to be considered a new account. I hear GYG and UberEats are flagging phone IMEI numbers of existing accounts so you can't use the same phone with a new simcard, so take care if you're going this route.
Dormant accounts might get vouchers too
i got WELCOMEAUS for $30 off emailed to me within 2 days of signing up for a new account
