The Sunnyboy was a popular Australian brand of flavoured ice block, well known for its distinctive tetrahedral shape (a design called a tetra-pak), sold individually or in packs. The ice blocks were extremely popular all the way through to the early 1990s, being cheaply available throughout tuckshops, discount stores and milk bars across most Australian states.
In 1980, the Australian rock band the Sunnyboys were established, with the ice block as their namesake,[1] to represent "bright, happy, young, fun".[2] In March 2013, comedian Dave O'Neil suggested that the company could ask the Sunnyboys to rename their band to one of their more marketable food product lines.[3]
