Our food regulations (particularly around best before and use by dates and the defintions of such) haven't changed significantly since the joint ANZFA food standards came into place in 2001. I spent many years implimenting these in a former life.
Cheese has a best buy and not a use by date because the product will not pose a food safety risk to consume after the date.
With cheese that would depend on type of cheese. Live culture cheese poses such a risk I have ben advised never to touch it irrespective of the best before date.
