So if you have your tickets why not just go and get a job with an earthworks company? Surely there are some of them in Mackay.
Before you go and try to get a job I would highly recommend adjusting your attitude. This is a public forum and by acting like you are on here you aren't giving any potential employers on here a reason to hire you. Having an attitude that only you have ambition because you want to earn 60k+pa at 17 is laughable. Take Warps advice, go and do what is needed and show employers that you aren't just a kid with a false sense of entitlement. Work ethic is the most important thing for employers especially when they are looking at hiring young people. Be realistic, you're 17, you don't know everything, you have very few qualifications and very little experience. What you should have as a 17 year old coming into the work force is a solid work ethic and a willingness to learn.
Good luck, hopefully you take some of the advice from this thread and stop being such a dickhead
