If it's pre-packaged food, you're generally able to get it in. If you need it you're better off playing it safe and declaring it but I haven't seen them confiscate pre-packaged food coming in from a country with reputable food standards.

Austraila is very hot on bio security and as such requires that you declare EVERYTHING food wise.
If you don't you can be fined $au 340
The Australian department of agriculture has a good website with information on it here

The thing I noticed was in particular that if you declare your items and they are not allowed all that will happen is the food will be destroyed. But if you hide the food the come down like a ton of bricks.
So take the bran with you, and declare it on arrival. At worse they willthrow it away.
If you have a favourite brand, and some oat brans are coarser than others, then you might want to have tour of austrailan supermarkets websites.
Coles, Woolworths, Safeway, and others
