So in theory if we find 10 amp tail not enough, the legit way would be to get an electrician to replace the dual 10A GPO with a single 15A?
No, you can't replace a 10amp GPO with a 15 amp one

As long as you have at least two power circuits in your house you can connect as many 10 amp GPO's as you like to them, though if you have too many items plugged into them at once you may trip the breaker - a 10amp GPO power circuit is usually run with 2.5mm2 cable protected with either a 16amp or 20 amp breaker

15 amp Gpo's have to have their own separate power circuits and the number you can connect to that power circuit depends on the size of the cable and the current rating of the circuit breaker protecting it - with 2.5mm2 cable protected by a 20amp breaker, you are allowed one, with 4 mm2 and 6 mm2 protected by the appropriate breaker you can have more - without a set of wiring rules to consult I not sure of the details

the wiring only needs an upgrade to go to 32A like an oven would require.

in theory yes, but in practice in Australia deals with 10A x2 vs 15A x 1 differently which may cause problems if its an old cruddy circuit.

With the EU Schuko 16A outlets the electrician can decide how many they want to wire to one beaker but usually they use a fairly thick wire so multiple are wired. In Australia for 10A apparently (for no good reason and its stupid), there is no such requirement afaik but for the 15A outlets there is and they have to be on a seperate power circuit or smth. So an electrician will refuse to change you 2x 10A for a 15A outlet.

I dont think in practice it makes any difference.

I went the whole hog and bought a spare kit from ModernSpare in the US - not a cheap option but with the distances and roads here a reasonable investment.
Come to think of it - I had a slow puncture soon after getting it and I had to put it onto the rear wheel while using my wife's car to take it to Jax for repair, so although it wasn't driven at least the jack etc was used!
