Getting a Job in Australia - Exploring Different Programs

Getting a Working Holiday visa is one option if you are between 18-31 and belong to a member country of the agreement. The explanation of the system and the member countries is on Wikipedia 

If you are open to migrating to Australia then:

Skilled workers and business people interested in migrating to Australia can be considered for a skilled visa by submitting an Expression of Interest (EOI) through SkillSelect.
An EOI is an indication that you would like to be considered for a skilled visa. An EOI is not a visa application.
You will be asked to provide a range of information in your EOI depending on the visa you want to be considered for, such as:
• basic personal information
• nominated occupation
• work experience
• study and education
• level of English skills
• details of a skills assessment, related to your nominated occupation
• business and investment experience.
These skilled workers and business people can then be found and nominated for skilled visas by Australian employers or state and territory governments, or they might be invited by the Australian Government to lodge a visa application.
All people interested in the points based skilled migration or business investment and innovation visa programmes will need to submit an EOI and receive an invitation in order to lodge a visa application.
For more detail on what questions and information you will need to supply in your EOI, you should refer to the webpage of the visa you are interested in.
