The Ethical Clothing Australia was intended to be a Certification Trade Mark. That's a special type of trademark that indicates a good meets certain standards (eg quality or manufacturing method).
However, the Ethical Clothing Australia mark was never accepted.
ethicalclothingaustralia.org.au 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?
