Also - locations:
Elwood is good if its not blowing too hard, westerlies = more chop, but in summer with a nice breeze its a great spot.
St Kilda Harbour - highly recommended when learning, wish I tried it earlier - not many boats moored in your way, provides a nice breakwall from too much wind when you wanna go and its blowing too hard, and when you comfortable tacking and jibing make your way out of it and along the beach.
Sandringham - well, is a little cramped, can be fun sometimes, but you'll grow out of it pretty quickly and find it easy to run into boats (cough - no names mentioned

)
Bonus level - Inverloch - great friendly crew down there - suggest joing their club - good way to meet experienced sailors and get tips - and awesome spot in a good wind because its not that deep and you can have some great runs.
Welcome to the sport and the beginning of a powerful addiction

PS - if you wanna sail with some beginners let me know - I usually go with Jermaldan on Sunday mornings, and Ozbiker56 when he's not kiting, and Architect when the water is bath warm :P
