Help Is it expensive to live in Australia?

Richie,all cool was just trying to give a reality check ,I'm 64 and spent most of working life traveling and working around oz mainly mining harvest fishing industrys and also operating heavy mechinary mostly off the back of a bike. on a 447 visa most employers arent going to want to employ you unless you have qualifications they need ie tradesman etc because in their mind couple of months and you will be gone ,so good chance you will be on the backpacker circit ,casual harvest ,now you can do the normal, team up with a van and a few people, trouble is lets say 4 people and only 2 jobs ,3/4 people tend to party more as well so will work out more exie ,this is not Ireland and doesn't rain as much especially during harvest areas during the seasons so a tent isn't a real hardship ,also found traveling by bike because a lot of people love bikes you will find a lot more locals will talk to you and tell you about work and who not to work for than if your with a lot backpackers in a van (and you will meet a lot more people because of a common intrest), and a group of backbackers generally have a what the what the .... attitude which doesn't help for work.and if this seems a bit know all ,for yrs a mate had a harvest labour hire company (a GOOD one,he did the proper and legal thing with the workers,unlike some/a lot) and I did the paddock bossing (mainly for the chance of a bit civilisation as most other jobs/mining etc weren't fly in fly out at the time ,a lot still arent) as well as a lot of other harvest work...best bet get a truck lic ...again good luck
