It appears the code from easternculture's deal https://www.ozbargain.com.au/node/193112 is generic
and applies a $25 credit to your Vinimofo account thanks to Uber. That is, it isn't a voucher code that needs to be applied to a purchase now, but rather $25 that you can add now and spend later.
To claim, simply add something to your account and then apply the code UBER23.
You won't need to complete the purchase, and the $25 will remain on your account.
Mod: Referral solicitation is not permitted/deal title should stand by itself without mentioning any referrals. Thanks.
