It does interest me as to why this is. I think it's this and maybe the geography/population making the mega supermarkets less viable.

I sometimes play with the idea of a food co-op to bring prices down, but haven't got far.

I think there is also some concern that the Coles/Woolworths duopoly is driving prices up. I usually avoid big supermarkets, but I haven't noticed any significant difference in price when I have visited them.
