In a statement released by Cadbury today, Caramilk chocolate bars have been "found to contain small, flexible pieces of food grade plastic as a result of a machinery fault during the manufacturing process".
The Caramilk bars containing the plastic may cause minor injury if consumed.
The affected blocks are those with a best before date of 17/01/2019 and 21/01/2019 only.
Anyone who has bought those Caramilk blocks are advised to return it to where they purchased it for a full refund. No receipt is required.
The recall comes after the chocolate has been selling out across Australia, with blocks being auctioned off on eBay for upwards of $20.
The blend of caramel and white chocolate was first on sale in the 1990s, before being discontinued after four years.
For further information on the recall, you can contact Mondelēz International on 1800 034 241 or visit http://au.mondelezinternational.com/contact-us.
