Zac,
Geez, in Melbourne there isn't a great number of places to choose from but the guys at Albert Park Golf Club (and the driving range) are good. They have a good selection of
clubs, aren't rip-off artists and they also do fitting at the driving range.
They're on Aughtie Drive, Albert Park and the number I had for them when I practiced there was 013 96964653.
If you're looking for a good teaching pro, I'd recommend anyone of the teachers at the Melbourne Golf Academy. They in Centre Dandenong Road in Heatherton near to Moorabin airport. They also have a shop but to be honest, I thought they were a 'bit too slick'... The whole MGA Centre is seriously impressive!
One final word: watch out for internet purchases. I'm not saying they're bad, in fact most of them a fantastic but you can't see or feel what you buy until they arrive. If you're buying something you've seen, then great ... if not just be careful to make sure you're buying the correct thing.
