I used the FLASH31 code from allisong's post to book and got 1000 Yums. I got greedy and wanted another 1000 Yums with another booking so I tried APP24 and it works. This code doesn't seem to be advertised anywhere.
Also note:
We have an important announcement to share regarding our services in Australia.
After careful consideration, we regret to inform you that TheFork will be discontinuing its operations in Australia. From March 31st, 2024, TheFork's local website and app will no longer be accessible.
We understand that this decision may come as a surprise, and we want to assure you that this was not a choice made lightly. Due to the significant impact the pandemic had on the global economy, particularly the hospitality industry, we therefore had to implement certain cost measures, which includes a reduction of TheFork's geographical footprint.
You have until March 31st, 2024, to redeem your Yums. Once this date passes, any unused points will automatically expire and will become inaccessible.
During this period, our services will remain fully operational, and you will be able to continue booking at your favourite restaurants with TheFork until 31st March 2024.
Book with a double YUMS restaurant for 2000 points. EG TGIF in Melbourne Central is one I have used in the past.
