Hi Colleen,
There is very little in the way of seed funding. The closest to this is COMET by Ausindustry, but to get that you need some serious IP. City of Melbourne grants are great as they are about the only ones targeting start ups.
Something that is very little know is business plan competitions. There is money available and all you have to do is submit a business plan. I have entered a business plan competition and I won $15,000 in cash and $15,000 in accounting services.
