Humphdogg, if you don't want to research, my I suggest Specialist Maths teaching + UMEP unimaths teaching at a school in Victoria? Good maths teachers are few and far between, and you appear to be quite passionate and knowledgeable about your subject matter. If you do not wish to become an academic, the most noble thing you can do is to enable as many as possible to become that academic that gives us the next mathematical revolution. You really would be better placed trying to entice as many students as possible into the mathematical world, especially considering our grave (and exceedingly worrying shortage).
Just a suggestion.
the problem with teaching specialist maths is that even at that level you encounter too many students who aren't particularly interested in the subject.
the challenge of getting students who have always been good at maths and liked it, to make the jump to liking analysis (2nd yr uni stuff) is much more interesting to me. it's at that level where students either decide that they want to do maths for the rest of their life, or to wimp out and retreat to something soft like chem or physics
i know that i was lost for the first few months of the analysis course i did last year, but after battling through it i realised that i enjoyed the challenge of the course and really liked the maths. and that's the point when i decided i'd like to do maths for the rest of my life 
and as for being an academic - well, i could definitely see myself doing research in the future. it's more that the lecturing is more appealling to me right now. that and i'm intimidated by the thought of having to contribute new and unique ideas to the fields that i'd be in 
Hey humphdogg, what state/territory are you in? maybe i'll expand the business there and you can express your passion in a much more fulfilling way! Imagine 200 students from a lecture coming down giving you pats on the back and high fives for giving them so much value in terms of your presence and content.
The base score of 45 is somewhat flexible. i didn't have the best understanding of my subjects back when i did year 12 and if i knew what i do know now, i would have done so much better. So i take that all into consideration. But the 3 most important aspect of working with my team is (in order)
1/ Passionate and energetic
2/ know the curriculum and content back to front and able to communicate that to the students
3/ willing to learn and adapt
this will be a team of passionate ppl, contributing back to society/year 12 and the dynamics of which will be hard to compare.
