there are jobs, most have specific skill sets. So at a minimum for a decent research position you would want/need honours or masters or tie it to a PhD study.
Research assistant is starting point and you need to have something to say you're experienced in its area of study or else why would they pick you? $40-65k depending on field, location, responsibility, lab level etc.
Head of lab or head of a program or something pays better, you'd need some solid experience (multiple years studying/researching area of expertise)
Top dog is you somehow become a national/world leader in development/study of your field. Pay is pretty good, usually based at a university. get flown round the world for conferences, get on TV for 20sec interview if you're special or make a break-through etc.
Problem is most research contracts are 6-12months. so much depends on funding. a lot of maternity leave contracts, but then back to square one when you're done.
My mrs wants to get back into research and has been looking for a job in melb for almost 12 months. A bit around in Sydney. My sister went into genetics instead, specifically IVF. Science degree, 2 diplomas and $75,00 in HECS later and shes doing alright. Not a huge selection of places to work, but once you've got your foot in the door... (pretty much sums up science)
...or do what 70% of science students do: become a lecturer, teacher, lab tech or assistant in a different field (petrochem, food, medical testing etc)
