Hey Frost,
I own and run the school at Pinnaroo Point, you are welcome to drop down the beach anytime and chat to us. We are happy to talk kiting all day so long as you don't interupt lessons.
We are about to sell off all of our school gear fairly cheap, boards kites, harnesses everything, even the rusty old trailer

so you might want to check out what we have, it will all suit you.
I would suggest you do a lesson with us so we can teach you kite handling, self rescue, water relaunch, self landing and launching and basic looking out for dangers. We'll custome tailor the lesson to you and teach you only the stuff you need to keep you and others safe.
The rest you are welcome to work out over time. You would also be welcome to borrow one of our trainer kites to get some flying time for gratis providing you take a lesson with us.
As for getting lesson for free off mates, that doesn't work.
A few myths: No one will teach you to kite whilst it is windy, they wil be on the water themselves.
Mates don't get you to practice self rescue scenarios, they may mention it in passing if you are lucky, it's not the same!
They also will not show you how to roll lines in the water safely.
They will not care how many times you do the walk of shame or screw up because they have nothing invested in you, an instructor is a professional, it's what they do, they've been there and seen every situation a hundred times so the lesson will go more quickly and you will advance faster and more safely.
A mate wont give you a helmet and life jacket and cover you with public liability insurance if something goes wrong.
Can't do much better than that.
Chatting with us is free everyday!

One thing though, in all seriousness, maybe bondo is right. If you cannot even afford lessons, then this probably isn't the sport for you. It is expensive. Very few people have only one kite, so be prepared to buy 2. Very few people are happy with ply boards, almost everyone rides a production board with a minimum price tage of $600 second hand if it is worth riding. A good harness will set you back $250-300
All up, being honest absolute minimum start up cost is :-
Kite bar lines (2nd hand ex school) $600
Board 2nd Hand $500
Harness (new) $220
One lesson $200
Cheers and good winds,
