The Ethical Clothing Australia was intended to be a <a href="">Certification Trade Mark</a>. That's a special type of trademark that indicates a good meets certain standards (eg quality or manufacturing method).
However, the <a href="https://search.ipaustralia.gov.au/trademarks/search/view/1524989?s=121d1b15-662e-41f9-9192-398638d40ef2">Ethical Clothing Australia</a> mark was never accepted.
Says in the headline:
"Assisting the local textile, clothing and footwear industry to ensure
Australian workers receive fair wages and decent conditions."
So it means that it is not a trademark but a seal of credit. It is given to brands that ensure that their workers get fair conditions.

I'm guessing it was made by Ethical Clothing Australia?
