Moving to Australia

Bazzers

Hi guys
This time next year I’m thinking of going to Australia as part of our construction management coarse we’re sent on work experience basically to get experience on a building site I currently work for a builder and have plenty of site experience.The placement is for half the college year & I was thinking of doing mine in Australia & staying the summer aswell so around 9 months in total .
Just wondering what advice can anyone give in regards what city to look for work in that I would actually come back having made decent money.

Where would be the best city to go trying to make money in Eg low rent etc ?
What’s the best way to fly in & out ?
I don’t mind what part I go to once I’m able to play football,go to the gym & there’s a decent nightlife
I’ll be 21 when I go out & if anyone can give me any advice on anything from travel,work,nightlife laws what would be the best visa to have sorted
It would be really appreciateed
