Hi Hurfi , you cant really go too wrong in St.kilda all the schools down here offer great programs and similar value for money.
If your after more reviews then hit up Melbourne Kiteboarding Hookup (MKH) on facebook , just be aware that "Some" schools will have a shed load of their own staff reply about how good they are
Saying that we would be more than happy to hook you up with some lessons , we offer some great packages and are the only Kiteboarding Australia Accredited School in Melbourne , We are also the only School in Melbourne that use Bbtalkin' action sports headsets in our lessons , google them , they make a huge difference in the time it takes for you to learn and how safe you are while learning.
We currently run beginner lessons in St.Kilda but once you are at the boardstart level we can offer lessons in Altona too.
I'am the Center Manager at Kitearmada , Anthony , Ant to you

and have just returned to Melbourne in 2015 after 15 years away in the UK , the Last 6 of which I was working as senior Kiting Instructor at Essexkitesurf School just 45mins out of London and one of the UK's longest running , largest and busiest Kitesurfing Schools. On a busy weekend we would have over a dozen Instructors on the water and around 200 punters , needless to say its alot busier/more popular than here.
Prior to that I taught snowboarding here in Victoria , Mt Hotham , in the early to mid nineties and then moved to Turoa in the North Island of New Zealand during the later 90's .
Anyways just abit of back ground on me , feel free to drop by the trailer in St.Kilda and have a Chat.
Regards
Anthony
