The dog food site here:
http://www.dogfoodanalysis.com/
does not update for years and years, and even when it HAS made a mistake, it won't correct or amend the reviews,
so that site IS a good start,
but, the site admins there do not seem real
up to date, imo. ..... I am not sure the site admins are even still there anymore. (?).
This one seems to stay up to date with current reviews:
http://www.dogfoodadvisor.com/
^DO look at the articles going down the side of the home page, too, after a while, you barely need to read a professional review, cuz you can learn which ingredients are GOOD,
and which ingredients are lousy.

^incomplete, but, very simple site.
Lists of quality dog foods that i *think* are available in Australia: (incomplete list, i just made list from looking around the internet, i have no idea of ALL the brands available in Australia, i can not find a site that is about Australian dog foods)
You can not do better than Raw feeding, if you can afford it. Clever ppl
do find ways to get meat at low costs, etc.
Or, even make your own dog food, like once a month, whip up a big batch, and add in veggies, rice or oats here or there as you have to, to create enough dog food,
and freeze it in freezer bags, etc. I have done this now and then, when i see some meat on sale, i cook it up, (my dog balks at raw meat)
add in some cooked softened up veggies,
some rice or oats,
and slop it into freezer bags for now and then changes in his diet.
I thaw it out, or give it frozen,
either way, my dog loves it.
Incomplete list Dog foods for sale in AU that are
okay, to good, to great:
(but, most of these seem pricey, imo) I *think* these are available in AU, but, i'm not sure.
Acana
Artemis
Black Hawk dog food
Canidae
Eagle Pack/ Holistic Select
Innova/Evo
Nature's Instinct
Some of the Nutro lines seem okay.
Nutrience
Orijen
Rotation
Wellbeing dog food
So-so dog foods:
Royal Canin---some of it's versions are not so great, but seems better than what you have now.
Merrick, some say it's great, some say it's so-so.
Dog foods i see are available in Australia that are
NOT good include Hill's Science Diet, Iams, Eukanuba, Purina, Dogpro, Pedigree, Alpo, Supercoat,
However, it seems some ingredients used in Australian versions of some of these brands may vary from other countries versions,
so it'd be better to have an Australian site to refer to....
sorry, i guess this is not helpful, and i do know what it is like to be on a budget, i do. I hope some Australian members come by here, and give you some better help.
