You are qualified for the Visa Waiver Program so rather than a visa, you may apply for an ESTA online. You desire a visa to go to Australia. Visa holders have the right to work so as to supplement their travel funds. If you're granted a visa, you'll be sent a notification letter that you need to take with you once you travel. Don't forget that you have to have an original passport as the visa is an adhesive document that you've got to stick within the pages of your passport. The visa has to be current and valid.
