In my Opinion there is no best possible route. Best Possible routes are relative as different people come from different backgrounds and have different goals. Some may enrol in universities with integrated CPL course to have a degree as a backup plan. While others would go full fledge flying as thats their main goal and they have no qualms over possible obstacles as they believe they can succeed. So to me the best possible route would be to find out what u can achieve and what is realistic enough for yr plans in yr aviation career, is being far an issue like u said parents and so on.. Is money the issue so that u have to choose msia over Oz?
