I entered a competition to Taste of Sydney Collective but didn't win the prize. Consolation prize was 2 free tickets to the Thursday night session which is going for $17 each (gives you entry and a free tumbler). Generic coupon code 'winning' in the email which can be used multiple times. Expires midnight Wednesday 31st October.
The actual tickets are from eventbrite but OZB seems to think it's an affiliate link so you'll have to click through to tickets from the Taste of Sydney Collective website.
Event description on their website:
A new festival in a unique venue
Taste of Sydney Collective is a new festival in a unique venue down at The Cutaway, Barangaroo Reserve. Experience four days of exclusive chef collaborations, exciting one-off dishes, a buzzing food hall and surprising live experiences. Visitors will be met with an unparalleled culinary adventure that will make them rethink the regular food festival.
looks like the code works for friday day session too
