Have you tried walking into a place and asking if they have any jobs available? My mom interviews and hires people a lot and says that she's more inclined to hire a person who comes in dressed nice and stuff. There are so many little things you can do to make yourself seem more hire-able, you know? Write a thank you letter after an interview and call the place after you've sent in an application to let them know you're still interested. Do you have a proper resume?

Is there any adult that could teach you to drive other than your parents?

Just a suggestion, but if you can't find any jobs at all in the real world, try something online. My mom may be going into vacation sales, because the housing market is piss-poor now.
Hope you find a job soon

Just keep persisting. Nothing you can do until you find yourself a job.

Maybe lower your standards a little if your having trouble. Go for the lower paying jobs, some money is better than none. Start small and work your way up. Certificate II in Retail is good to have but at your age it isn't highly recognized.

If you give up your not going to go anywhere and in a couple of years you will regret it.

By the way, where exactly in Queensland are you from?

Why can't you leave without money? Where does this perception come from that you need money to leave? As weird as it is for people to consider it isn't unrealistic to find something in another city and than leave and there are all sorts of ways to leave with minimal financial costs. If you're looking to leaving the city you should consider looking into where you want to go, what you can do before you get there and alternative and cheap routes to arrive.

I'd also suggest just borrowing the car and learning to drive. You're in a small town, my 14 y/o sister drives around in a car she bought with money the family gave her and she doesn't even have her permit yet however due to where she is she has no fear of anyone stopping her like in a big city. You can easily learn to drive regardless of the law because of the size of where you live.

But most of all I have to ask why are you stopping your education? What is the point of it? So you have some certificates of training? It isn't even a two year degree its not going to carry you anywhere its just like a gold star in kindergarten. You should be looking towards a stable future by remaining in school, most careers won't get anywhere without a Masters degree in today's highly competative and diminished economy and while you're on the road to that you have a host of scholarship and grant options that will keep money in your pocket. There are very few good reasons to end your education at High School and you don't seem to have one, I feel that it is important that you reevaluate what you plan for your life long term.

Why would you take a job after you graduate school that promises 15 hours a WEEK?

While I unfortunately can't give you any advice on financial aid as you're an Aussie I'm sure there is a wealth of Government money and private scholarships which you can apply for and you should look around for some. Even going to college can be done online these days. As for rent and such, there are many people who accept live in house keepers you can exchange services such as childcare, cooking, and cleaning for a room to rent and you can find these in classified ads, the internet, and craigslist.

There are a lot of options out there and you just need to take a look around.

You accepted a job that offered you 10-15 hours? That cant get you anywhere in life.

And for your money problems... financial aid. You can get a full ride to certain community colleges and even universities if you're really that deep.

Well to go to college you'd need money anyway, and since you're in a small town even with a degree you probably wouldn't have much work choice either, meaning you wasted another 4-5 years in school, and spent 30K...
