In Australia, data jobs have a high floor but a low-ish ceiling at most places. Salaries start at around A$100K if you know how to interview, but 30 years of diligent practice only nets you around A$200K, and this would be considered an extreme success.
If you're already good, just have coffee with executives/leads at places that take engineering seriously and you'll earn well, but there's no need to enter data hell as an employee at the typical company.
