Da kann dir die immi Seite weiterhelfen:

Business assets

You (and your partner combined) had net assets in a qualifying business of AUD200 000 for at least two of the four fiscal years immediately before you apply.
Business turnover and ownership

The annual turnover of your main business (or two main businesses combined) must have been at least AUD500 000 in at least two of the four fiscal years immediately before you apply.

In addition, you (and your partner combined) must have owned at least:

51 per cent of the business where the turnover is less than AUD400 000 per annum.
30 per cent of the business where the turnover is AUD400 000 or more per annum.
10 per cent where the business is a publicly listed company.

Total assets

Your (and your partner's) total assets have a net value of at least AUD800 000, and were legally acquired and are capable of being transferred to Australia within two years of being granted this visa.

You have sufficient assets (additional to those above) of at least AUD100 000 to settle in Australia.

Und ausserdem:
In your business you must also do at least one of the following:

develop business links with international markets
create or maintain employment in Australia
export Australian goods
produce goods or services that would otherwise be imported
introduce new or improved technology
add to commercial activity and competitiveness within sectors of the Australian economy

You may be asked to complete a monitoring survey to provide us with information about your business activities in Australia.

Was ich allerdings gar nicht verstehe:
