Hey there, the quoted sentence is not a precise interpretation of the law (albeit is is written by a regulator). You could read the law at s47 - 48 at http://www.austlii.edu.au/au/legis/cth/consol_act/caca201026... and probably argue either way with your examples. If you think of a "combo" or "bundle" as a separate good to the individual items then those examples are unlikely to be covered.

In reality though, these laws are intended to prevent misleading price representations, not to force businesses to calculate the best deal for their customers.
