10mins wins for me even if its more expensive.
The PPL your bullet proof with and requires minimal training if you want to fly microlights etc. The PPL is an ICAO license so will have maximum possibilities to use abroad. To upgrade the lesser licenses to international ones will easily cover the extra.
But the big thing is the length of drive. 10 mins you can pop in for an evening lesson if the wx is good. There might also be ground school in the evenings. Bad wx and you haven't wasted the day going for a lesson. Fuel will soon mount up. You can get the first flight of the day early slots before it gets bumpy without having to get up at the crack of dawn.
After your qualified and can take pax driving to say perth is more of a day out and if it doesn't pan out you can go do something else instead so is more manageable if you decide the WX isn't good enough.
