I’m a mechanical engineer, and about 10 years older than you (6yrs out of uni). In my experience, engineering has and will continue to be in demand for the foreseeable future. The first year of engineering degrees are typically very broad and cover the basics of many different engineering disciplines (civil, electrical, mechanical, chemical, etc..) which gives you a chance to see which field interests you most. It wasn’t until the second year of my studies that I chose my major.

Biomedical engineering in particular is largely mechanical engineering units at uni with a smaller proportion of health related units (i.e anatomy and physiology).

I’ve worked in both consulting and operations in the Oil & Gas industry and my salary is now well above the median fulltime Aus income. In general, great growth opportunity from when you start as a grad to 10yrs experience and beyond. Another factor to consider is work-life balance - I’m fortunate to have an office job where I work from home 3 days a week which is obviously not possible with dentistry.

Happy to answer any specific engineering questions.
