These are the sites I could think of, off the top of my head:
This is not to disparage the course or the business: it seems to work for the OP and her students.
There is a problem, you fill that problem and people are willing to pay to have that problem solved.
"Quality of experience" really starts playing a role with competitors.
If you are resident in Australia (or the company's primary business operations are conducted out of Australia), Australia will tax you - doesn't matter if your company is nominally registered in Singapore.
I assume the founder relocated to Singapore - if she's just running the Singapore company while living in Australia, she's just not complying with the tax law.
Well you'll be taxed on your income, but the company won't be taxed by Australia.
I can't register a Singaporean company, conduct all business physically from Australia as sole director under the banner of that company, and not pay Australian tax on the company's income (or GST).
Well, of course you can try and do this - but it's illegal, and if the ATO finds out, you're in trouble.
It doesn't matter that you don't pay yourself a salary or declare dividends. If the company's principal operations are conducted physically from Australia, it will be deemed to be an Australian tax resident.
Now, different story if the company has a physical presence in Singapore - say, your cofounder/codirector works there with a few other employees). Then, the company's Singaporean presence might be substantial enough that the company is not deemed to be a Australian tax resident. Then you would only pay Australian tax on your personal income/dividends.
Similar story if you're the only one conducting the company's operations, but you do so physically outside Australia for more than 6 months of the year.
In some jurisdictions (e.g. Hong Kong) companies pay tax only on domestic income. So if all your customers are outside Hong Kong, there's no tax to pay.
However, the owners of the company will usually have to pay income tax on money they receive (as salary or dividends) wherever they are tax resident.

She seems to be mixing up 'approve' and 'prove that'.
