"That, I think, tells us something about the level of competition here."
"It's very difficult to get to the bottom of that. The profitability figures do give you some very broad picture of what's happening, but the issue of price gouging isn't one we were able to engage in too closely."
"We use the term oligopoly because it basically implies that there's not a need for the participants to compete strongly on price,"Mr Keogh said.
"It's no wonder consumers told us very strongly that they find pricing very confusing, and therefore very difficult to make good choices about what to purchase."
