I poked around the web a bit, and could not easily find a pencil/paper home OG program similar to AAR/AAS. I did, however, find Nessy (www.nessy.com), which is a gamified online OG reading/spelling intervention developed in the UK. Reviews by users of both Nessy and AAR describe them as very similar in fundamental approach (other than the game elements, obviously), as one would expect from two OG-derived curricula.
From what I can glean, you can set it to British or American spelling/pronunciation, which suggests that it might work for Australia. At least it may be better than an American curriculum. The specific subscription product:
