After the research I have done, I have come up with the following
The HKAC charges 35,000HKD as a joining fee. 20,000 of which is to be paid in 4 months as the rate of 5,000 per month. The remaining 15,000HKD can be paid when you are 28 years of age.
The cost of the plane it self varies on the model, the Cessna is at 1,600HKD per hour.
The ground school and instructor are provided free of charge
Other flight schools such as those located in Geelong approach a similar price.
The cost of living abroad, travel, visas & other costs significantly increase the overall price of completing a PPL out of Hong Kong. If I then want to fly in Hong Kong I not only have to undergo a conversion but also have to join the club to fly privately, therefore it made more sense for me to simply undergo my PPL here in Hong Kong.
Finally, there is school, a year into my 2 year diploma which I need to stay in Hong Kong to complete.
I hope this provides people with some insight as to why I have chosen this option instead of the alternatives.
