You can say whatever you want when you sell stuff in Australia, another set of laws (what we are talking about here trumps it). The most obvious case is warranties, you can take an iPhone back after 2 years with a 1 year warranty, and they have to fix it free. You can take expensive TVs back like 3 or 4 years after the warranty ends and get a repair for free.
