I have a maths degree from Australia, and have always worked in software development. I also have a Grad Dip Science in computer science.
The job market over the part 20 year has been 'patchy'. There have been good years, and other years where I had to move interstate for a while to find work.
I'm now just about to complete a 1 year teaching degree to teach math/science in high school. Not because I like it but because of job security & job burnout from developing software.
- everybody who graduated from my maths degree in my year went into software. One works in the Australian Bureau of Statistics. Each state govt has a stats bureau eg I've worked at

- there are really no applied math jobs. Companies need problem solvers, and they don't see maths as the right skill set (eventhough that's wrong). I recommend you move into software development/design.

- an undergrad degree is now just the starting point these days, you will find the higher achievers in organisations have specialist postgrad degrees. (In Canberra this is especially so, everybody seems to have 2+ degrees). Get a masters degree in a tech area. It will make job searching easier.
- get qualified qualified qualified thru short courses. Even Microsoft certifications, project management certs etc.
- have a look at an engineering qualification, such as a 2 years engineering masters degree (I'm looking at the degree at the Uni of Southern Qld, which will admit you to an engineering masters even if you have a science degree)
- I've worked in the Dept of Defence as a contractor, it was great fun. Think about applying to the Defence Dept in Canberra direct as a civilian employee. Have a look at Defence Science & Technology Organisation, but you need a PhD to advance there.
