ppl in phil.
Actually OZ sounds like a great deal, but if your friend wants to be close to HK then coming to here to Flip land is a good choice.
Words of advice though; i got my ppl and cpl here in Manila, but my atpl, i acquired in the USA. Not that I want to put down the flying schools here, but I found the quality of instruction a lot better in the USA, not to mention the total flying environment. If your friend is serious about flying then he should not skimp on training and always get the best he can within reasonable means.
Just my 2 cents.
