I don't think anyone is saying that flying in Australia is utopia.
But the majority of people born here are more than happy to settle down and make a career at home. Some may have different dreams, and the flexibility and motivation to travel to other countries and jump through their hoops! Good for them.
Having done the hard yards with foreign licensing and getting to know your new neighbours, there's plenty of incentive to make a go of it.
But it won't work out for everyone.
