"its a lifestyle, not a way to earn a living" I hear it so often and so often I think...what??? Writing novels from a south pacific island while collecting money from a trust fund is a lifestyle. Being on your feet 15hrs a day, dealing with medicals, complaints and hungry people is a job. And personally if it's a job I expect to be paid properly for it.
Asking for the average income in Australia is hardly the equivalent of wanting to be overpaid for what you do. So lets keep the Donald Trump references to ourselves. It's not selfish to expect an income on a par with what the rest of the country earns doing much easier work.
