The ANZSIC Code  of "Aged or Disabled Carer" code under "Description of main business or professional activity"  does not exist. Please pick another code from the ATO list - https://www.ato.gov.au/calculators-and-tools/business-industry-code-tool-anzsic-coder 


Note: The codes for item P2 “Main business activity” and item 1 “Salary or wages (PAYG)” are different. They are ANZSIC codes and Occupation codes accordingly.
