Hi Dave,
All of your activities listed in your question are in the public realm.
I would watch the Mini Course – Foundational Knowledge (under the knowledge tab)
Also, being self employed, I would recommend watching modules below
(under the knowledge tab – scroll down to see the page to see the video)
Module 1D – Integrate Running Your Business In The Public With The Private Realm And How To Run A Business In the Private Realm.
Module 1B – Steps in the Transition from the Public to the Private Realm (Part 1)
Module 1C – Reside & Conduct Business Within The Private Realm, Impact Upon Your Business, Finances & Life. Interaction With The Public Realm
Module 11 – Cashflow v Living Costs – Simple Steps To Dramatically Improve Your Financial Disposition
In the Private Realm, you could have a Non-registered trust ($1,650) and funnel the cash that does not have any GST added to the sale or service into that account. Because the cash is for your sustenance (not income – dangerous word) it is outside the ATO. (under resources tab you can read up and watch videos on how trusts work. See if it would benefit you)
When you have an ABN – that is public
When you have a bank account the ATO can see that too.
When you have an employer they can see that too. The tax module can show you how to fill that in.
Cheers, Cherie
PS. After you have done some research and you still have questions. Ask Mark in the Wednesday night Q&A.
