Hi there - Basically there is no such thing as packages in Australia. There are certain features that come with the different models, for example the 335i will include the upgraded stereo, nav system etc. Then you basically choose from a menu of all the remaining options individually. Its a long list full of large numbers hehe.
So comfort access is a standalone option in all models I believe.
If you download the brocure from the AU website, it has a matrix at the backthat tells you what features are standard on what models....prolly a good place to start.
hope that helps.
