That's where 4Corners report misses the mark. It didn't show where the price increases really came from. It comes from the general 15%, 20% or more increase since 2021 in overall cost of producing the goods on the supermarket shelves. This in turn comes from the above average increases in wages, rent, electricity, etc.

If Woolworths were really price gouging, that is, increasing prices while paying suppliers the same, their profit margins should have increased since 2021. But in reality, they're more or less flat. There've been no big expense increase in other areas like advertising, that I'm aware of. So how can they be price gouging?
