How to apply for an Australian tourist visa without a work certificate?

If you are starting a business, you can't provide proof of employment and operation. If you apply, you can only be unemployed (you can also provide running water certificate and half-year time deposit). RV products can be provided as auxiliary materials, and purchase contracts or invoices can also be provided. Your boyfriend is German, you can't guarantee it. You are just boyfriend and girlfriend, and you don't go to Germany. It is ok to have a history of leaving the country.
