Get the cheapest thing....they end up choosing where they sleep lol! My DS probably slept a total of 24 hours in his bassinette...the rest of his newborn first months was spent sleeping in my closecarrier sling or in bed with me. We spent too much money on cots and bassinettes that just didn't get used.

ETA- on the question about being in your room or not, here in the UK they recommend that your baby sleeps in the same room as you (cot, bassinette or safe co-sleeping) for the first six months as it reduces the risk of SIDS. Not sure what the advice in Australia is but I guess it would be similar.
