In north-west Sydney I likeFlour:
Last year I ordered 25kg of flour from Santos Trading
- it's not bad, but it's not the bakers' flour you're after.
This morning I did a web search and after some poking I found: Plateau Foods
. They carry Manildra and Allied Mills bakers' flour in 12.5kg AND although they're a wholesaler you don't need an ABN to buy from them. I've never used them, but their Silverwater warehouse is open on Saturdays, so you could at least get a sense of the place.
I also understand there's a place in Artarmon called Oriental and Continental Foods that might carry what you're after. I haven't been there myself, but I think I've seen it mentioned elsewhere on eGullet.
Oriental and Continental Foods, 41-43 Carlotta Street, Artarmon, 9906 8990Bits and pieces:
Dijon Foods - Unit 6, 8 Gladstone Road Castle Hill (they also have a shop in Carringbah)
They also do restaurant supply, so it's a mix of huges tins of sliced beetroot and other more 'gourmet' products. They also have some refrigerated/frozen stuff. I find their prices for nuts are really good (no flour supplies so far as I can recall).
Martelli's Fruit Market Rouse Hill - next to Coles
They have a pretty amazing range of products (across several ethnicities) and I love having a wander. They're also generally got really good fruit & veg.
