I will answer very quickly from, again, the definitions that underpin the communications policy and the directive on communications. Non-partisan means objective, factual and explanatory and free from any political party identifiers or slogans. The primary colour of the governing party cannot be present, unless an item is commonly depicted in that colour. It cannot carry the name, voice or image of a minister, member of Parliament or senator. That's the definition of non-partisan.
