^^^ As above, unfortunately you'd be lucky to get 2 good days of wind between now and July.
I was the only person out at Pinnaroo point on Saturday last week, nothing for about a month before that, and even though I brought the right kite for the conditions, I was struggling for enough consistency to avoid drifting downwind. Needless to say, the conditions were inappropriate for learning.
My own personal advice, would be to go to Bali (
ripcurlschoolofsurf.com/courses-reservation/kite-surfing/). I learned there, they have a boat to drag you up wind which is amazing when you're learning, and after attending schooling in Tarifa and England, I would have to rate my experience in Bali the best.
I was actually standing up on my third lesson (the first one where they let me use a kite in the water), but that is by no means a guarantee. And indeed, I benefited immensely in Tarifa from practicing water starts with just my feet dragging on sand. But the instruction was good, I just didn't get enough of it.
There was also no lesson if the conditions were unsuitable. Something that I have unfortunately not seen other schools doing.
The wet season is pretty much wound up right now, and although it doesn't look like they have particularly impressive winds at the moment, next Saturday and Sunday afternoon look like sweet predictions (
www.windguru.cz/int/index.php?sc=208480). That should give you enough time to buy tickets and book somewhere to live.
School holidays don't kick in 'til the end of June either, so accommodation should be cheap if you slip in asap. You will probably find that it doesn't cost all that much more than where you're currently renting as long as you don't stay in the tourist districts. Although it would be cheaper again if you could split the bill with a +1.
If you want to fit in 6 good days of kiting, I would be looking at maybe 3 weeks in Bali, just because winds are not consistent, and because when I was learning, 2 days of consecutive kiting was just murder.
