Volunteer and Work in Australia
Australian citizens, New Zealand citizens and permanent residents of Australia can work in Australia without any further permits, but others will require a work visa. All visitors who do not hold Australian permanent residency or citizenship (including New Zealand citizens who aren't also Australian permanent residents or citizens) are not allowed to access Australian social security arrangements for the unemployed, and will have limited, or more usually, no access to the Australian government's health care payment arrangements.
Payment and taxes
Most Australian employers pay via direct deposit to Australian bank accounts. Open a bank account as soon as you arrive. Your passport will be enough ID to open a bank account. And with it you can have an eftpos card and a visa debit. For it also you need to give an address in Australia.
As soon as you have an address it is wise to apply for a Tax File Number (TFN). You can apply for it online (though, only in Australia) for free at the Australian Tax Office website web, though you can generally get it quicker if you just go to one of their offices. The Australian financial year runs from July 1 to June 30, and tax returns for each financial year are due on October 30, four months after the accounting period concludes. Check with Australian tax agents about Australian tax liability and filing an Australian tax return.
Australian employers will make compulsory payments out of your earnings to an Australian superannuation (retirement savings) fund on your behalf. Temporary visitors who are not citizens of either Australia or New Zealand can have this money returned to them web when they leave Australia.
Working holiday scheme
Australia has a working holidaymaker program for citizens of certain countries between 18 and 30 years of age. It allows you to stay in Australia for 12 months from the time you first enter. You may work during that time, but only for 6 months at any one employer (was 3 months until July 2006). The idea is for you to take a holiday subsidised by casual or short-term jobs. If you're interested in a working holiday, some useful skills and experience might be: office skills to be used for temp work; or hospitality skills to be used for bar or restaurant work. An alternative is seasonal work like fruit-picking, although much seasonal work will require that you work outside the major cities. Working for 3 months in seasonal work will allow you to apply for a second 12 month visa.
You can apply online for a working holiday visa web, but you must not be in Australia at the time. It takes just a few hours to process usually and it costs about $270 (as of July 2012). On arriving in Australia ask for the working holiday visa to be "evidenced", so you can show your future employer.
Sponsored work visas
The easiest way to get a work visa is to find an Australian employer who will sponsor you. However, this is just 'easier', not 'easy' as such. Your employer will need to demonstrate that they cannot hire anyone with your skills in Australia, and the approval will take several months. If in search of sponsorship, be prepared for a long wait. Note that getting the visa might take a couple of months from the beginning of the application process, and that you will need a medical examination by a doctor approved by the immigration officials before it can be granted (among other things, you will need a chest x-ray to show that you do not have tuberculosis). Check with your local Australian High Commission, Consulate or Embassy and the the Immigration Department's website web.
You can apply to immigrate as a skilled person or business person, but this process will take longer than receiving a work visa. You can also apply for permanent residency as the holder of a work or study visa, but your application will not be automatically accepted. After four years of permanent residency you are eligible to apply for Australian citizenship.
There are several volunteer opportunities in Australia. Many worldwide organisations offer extended travel for those wanting to volunteer their time to work with locals on projects such as habitat restoration, wildlife sanctuary maintenance & development, scientific research, & education programs.
