You can take advantage of all your connections and charge some tuition fees first. The consumption there is very high. It is difficult to find a solution if one person lacks funds. The masses are very powerful, so you can solve some of your urgent needs first.
You must know when to leave before you leave, so do more work, do odd jobs, save the money you earn and make full use of the winter and summer vacations. A little money saved by yourself can also be used as the cost of studying abroad. You can ask your parents for the rest.
You should be familiar with life there. As far as you are concerned, estimate the cost of living there and get familiar with the environment there. Think about yourself when you get there. What kind of work do you want to do to make up for your living expenses is to earn money through work-study programs.
There must be a lot of people who want you to go out to play when you go. You should know your actual situation and go out to play moderately. If appropriate, you can relax and contact the feelings between your classmates. If the cost is too high, refuse decisively.
Our age is just an age of fun. There are many new things I have never seen outside. However, these things need money to buy. Restrain yourself and buy whatever you need outside. If you don't really need it, just want to watch it for a while, don't.
You can also do a little business there and introduce your own specialties to Australia. Maybe you can earn a living by this.
In short, by all means, I can successfully complete my studies.
