I would love to know the answer to this as well. Are Blackwater still recruiting ?

what is your career now, and age?

 Not wishing to stir you up ..... but the only guarantees in life I know of are death and taxes. It's a big ask to work out what work will keep you in employ for ten years, especially given the present business adjustments and the increasing use of 457 visa workers to displace ordinary Australian workers from their jobs.

 Sheriff/ debt collector.

 I done this back in 2010 getting my TAA and OH&S Cert IV, but that certainly didn't mean I could get a job straight away, I had to wait and I got a job that kinda fell into my lap. But it makes me very angry seeing some of these training places advertising Cert IV WHS and get a new job doing Safety. Unless you know someone, it ain't gonna happen. And a couple of years ago, you needed 2-3 years doing safety to get a new position, nowadays, they want 5 years experience.

Whowww. that's a hard question.

guarantee for 10 years....seriously don't know many of those sorts of jobs without doing a uni degree and becoming a doctor engineer etc etc.
really not enough data for any sort of answer here.

does the 10k go straight to a training course, or does it have to support you (and family .....7 kids???) while you do the course and not earn?

think you have to ask yourself ...are you mechanically minded? or more people orientated ? along with a big list of other questions.

Seriously...might help to write down what you like doing and what you don't. interests etc and be brutally honest with yourself so you can at least narrow down what you don't want to do.

 Way the jobs are going the crime will jump. You'll be outdoors, bit of running, shooting, drifting and a street fight or two!

Then you could go the other way and be a prison guard. 

Some good advice here re thinking hard about what do and don't like, to answer previous questions: my background is IT / project / planning and analysis and the 10K would be put into a course. So when work dries up which inevitably it will, i have something to fall back on. The other thought / brain fart i had was buying a piece of machinery and either hiring it out or building a small business using it rather than investing in a course? Perhaps a sand blaster or something like that, i just gave to try and work out where the demand / shortage is so i don't enter a crowded market?

Keep away from jobs that are tied to recreation, discretional spending as those things are going to be under the pump as people tighten the screws on their spending in the winding down of the construction FIFO jobs.

You want a job that will keep you employed for 10 or so years, forget taxes the government is laying off people right left and centre.

Now that leaves death, questions to ask yourself. Can you handle highly emotive situations and be calm and pleasant, be customer focused at all times. Look good in a suit and tie, you have the computer skills, got a clean drivers licence, have good language skills (not foul) and a pleasant personality.

Yeah, then my suggestion is look at the funeral industry, get on a course as a mortician or embalmer because as shore as the sun rises in the east people are still going to be dying in 10 20 50 years time.

A mate of mine started in the business some 15 years ago, after 8 years he started his own business, got brought out by the big boys in the game, ended up with a not insignificant chunk of money the company that brought him out kept his business name and he is still doing what he was doing with no cares in the world he's laughing all the way to the bank.

Just a suggestion

 Never run out of kids to teach

Interesting and very true meglodon there will always be work in death. Not sure i could do it. Will explore buying some cool piece of machinery or device? Teaching is also something to consider, but to much study is required and having worked in a school id be to grumpy me thinks

Mate I say follow your passion and you cant go wrong, the last thing you want to be doing is doing a job you dont like. I was in a similar situation a few years back and as fishing was my passion I set up my own business and havent looked back. It started out as a part time thing but now its all I do and I make a comfortable living out of it and most importantly love what I do.

when I got hurt at work , I have a 21yo girl allocated to me to advise me as to what my work options were, she suggested Tafe as an elect instro instructor , my response was bugger that I couldn't put up with the shit heads , 35 years ago it might have been an option when you got 15yo kids as appys and you had a chance at changing their attitude , these days appys start when they are 21 to 30 and already have their attitudes well developed

 And there attitudes.

 get a digger with 2 buckets,dig footings for granos,put soak wells in ,if you get good, the sky is the limit easy work could be good return.even dig trenches for prop owners for power to houses,not hard work just a idea,good luck in your new adventures

Most important thing is that you enjoy your job and that it provides the funding to support the lifestyle you really want. 

A business can (generally) offer better cashflow and more free-time than a job.

I started my business from scratch recently (Tax Agent) and after struggling for 12 months, I can now choose the days/hours that I work (usually coincides with bad weather days).

I love working with business start-ups and would be happy to discuss any business ideas you might be considering. First meeting is typically free.
