I'm in Perth, Australia.
The job I was referring to to was a retail management career (yes, a lot of retail management jobs top out at $50k, but there are also plenty in the $70-$100k range.) This is also a quicker than average (but I know people who've done it, and assume I could have too) progression in this job. I know a number of people making $70k+ in retail management.
Other well paying jobs that don't need a degree would be:
Most trades - electrician, plumber, heavy vehicle mechanic (likely to pay $70k in the city but well north of $100K if done in the mining industry. Electricians can make $200k+ a year.)
Other mining related jobs - e.g. driller, truck driver etc, health and safety rep on mine site.
Recruitment Agent (start at $50k, can work up to $100k within 5 years if ambitious).
Real Estate Agent (Average commission per house $15k, you keep half and pay half to your employer... how many can you sell in a month?... with 5 years experience 2+ a month should be easy to do.)
Computer programmer (non-qualified): start at $50-70k (depending if you have certifications or not), withing 5 years $100k would be easy to do.
Executive assistant: start on $50k, with 5 years experience $70K+ would not be unusual.
Payroll, Accounts Payable, Accounts receivable Team Leader: Start on $40k as a clerk, $90K for someone with 5 years experience managing a small team would not be unusual.
Wages in Western Australia are scary high - average full time wage is something like $76k and minimum wage is $30k. (However the $76k is massively skewed upwards by qualified and experienced people... $76k is still a good wage for an under 30 year old.)
I guess the thing for you to do might be to compare your job opportunities in software with/without the degree. If you can get a job without the degree, you might then be able to use your employer's tuition reimbursement program to get/finish the degree. I know someone who is doing this. She paid for some certifications, started working in IT (helpdesk), is now studying (paid for by company) and will move to programming when she has finished the qualification, if not before.
