I think you may have some facts wrong in respect to less-than-16-day loans, and the 20% establishment fee. According to https://www.moneysmart.gov.au/borrowing-and-credit/consumer-credit-regulation:

• Short term' loans of $2,000 or less that you must repay in 15 days or less are prohibited.
• Fee limits on small amount loans ($2000 or less)
  
  From 1 July 2013, fees charged on small amount loans are capped (that is, limited to a maximum amount).
  
  Credit providers can only charge you the following fees:
  
  - A one-off establishment fee (of not more than 20% of the loan amount)
  - A monthly account keeping fee (of not more than 4% of the loan amount)
