Thanks for the replies so far.
It isn't all that much food actually, We eat a fair bit of fruit and vege, and meat prices are not that great at the moment. The drought probably has a bit to do with that. To rough it out, we spend around $70 on fruit and vege, $60 on meat, and around $70 on everything else, such as sauces, eggs, rice, pasta, spices, baby stuff, laundry powder etc.
FYI beef prices are anywhere from $6/kg for low grade high fat mince, to $20/kg for top grade steaks. Assuming the only meat product purchased was beef (at $10/kg for example), that would be around 6kg per week, for two people, or around 400g per day, roughly 2 serves.
Certainly nowhere near 2g/kg protein, at least not for me, it is probably close to 1.5g/kg for my wife.
Chicken prices are similar. I have started to buy turkey and kangaroo for variety, and because it is cheaper.
I need to locate a cheaper place to buy meat and eggs from, or become more of a tuna junkie....
I would be interested in some info about the meat wholesaler you spoke of.
