Footwear retailer Betts was among brands named and shamed in a controversial annual report.
Baptist World Aid has released its latest fashion study, grading 106 apparel companies on supply chain transparency.
The report has previously received backlash over its questionable reporting methods.
This year’s report argued major grading disparities between multinational companies such as Zara (A grade), versus Australian headquartered brands.
Betts scored an F for being non-responsive to the research and demonstrating no transparency.
The proportion of companies looking to improve wages continued to rise from 11% in 2013 to 42% this year.
Since 2013, there has also been a 30% improvement in companies tracing second tier suppliers, while two and a half times more companies (45%) trace raw materials suppliers.
