Taste.com.au was among the first to spot the limited edition chocolate blocks in grocery stores, while eagle-eyed shoppers have also shared their finds on social media.
CADBURY CARAMILK SPARKS FRENZY
Last month Cadbury confirmed it would be bringing back Caramilk after overwhelming customer feedback.
"We've listened to the tens of thousands of Aussies asking us to bring Cadbury Caramilk back," Cadbury marketing manager Katrina Watson said.
"We couldn't ignore their passion for our golden chocolate block, so we're proud to be bringing it back."
Cadbury's Caramilk, a hybrid caramel and white chocolate bar, was part of the chocolate brand's line-up in New Zealand and Australia until it was discontinued in 1994.
It came back in Australian supermarkets for a limited run in early 2018, however blocks of the precious golden chocolate were hard to come by.
However in New Zealand, the Caramilk was brought back to Kiwi shelves from September.
