Sam as you live IN Melb -as you aren't far from bintel 9x63 is a good size..but if you divide 63/9 = 7mm exit pupil. IN melb you are never going to be able to take advantage of this, as your own pupils will not open fully to 7mm (in a city its more like 4 or 5) - though for a beginner this can be confusing. in saying that though 9x is a really good magnification to hand hold & when you get to a dark country sky you will be able to take in all of the 63mm aperture (size of glass).
For this reason i would recommend a 10x50, something like a pentax pcf - which has the advantage of being waterproof/fogproof
If anyone is interested i could bring several pairs of binos to the Kangaroo Ground War Memorial Lookout Tower on eltham/yarra glen rd on one night this weekend - you could compare sizes & different magnification
