Can I go back to Australia again on a working visa?
If you’re talking about having been here on a working holiday visa and you didn’t work for 3 months doing seasonal work in a regional area, you have no chance of getting a second visa. Working holiday visas are only for 12 months. As a special consideration for applicants from the UK and a few other countries, if you fulfill certain strict conditions during your first visa, you can get a second visa. If you didn’t meet the special conditions (of which you would/should have been aware), you can’t reasonably expect to receive the special consideration. Even if you had worked, if the work wasn’t seasonal work for a primary producer in a regional area, you wouldn’t be eligible.
