There's a good example form here on VJ, check it out: http://www.visajourney.com/examples/INS-Form-G-325A-aos.pdf
AOS does look confusing in the beginning, but read all instructions, and the guides here, make lists and quadruple-check everything.
There are some guides from VJ members, too. I personally found Vanessa&Tony's guide incredibly helpful. Here's a link to it: http://www.visajourney.com/forums/topic/235331-aos-ead-ap-from-k1-the-aussie-way-doc-list-included/
