In 2013 this company paid two infringement notices totalling $13,200 and changed the labelling of its "floor stock" or "shop soiled" furniture. This occurred following Australian Competition and Consumer Commission allegations that Super A-Mart was making misleading representations regarding the application of the consumer guarantee provisions in the Australian Consumer Law (ACL) in relation to floor stock furniture offered for sale.

In 2014 this company was fined a total of $30,000 after two employees were injured when an elevated work platform toppled.

Quadrant owned Rockpool Dining Group, a giant in the hospitality and dining scene, has been accused of "one of the most egregious cases of wage theft Australia has seen yet" by a law firm alleging the company has underpaid its workers at least $10 million.

Quadrant bought a large stake in Independent Pub Group in 2007, which owned several hotels, including gaming venues. Quadrant has since sold its stake in the hotel group.

In 2025, Quadrant Private Equity’s Affinity Education faced allegations of a toxic workplace culture, marked by cost-cutting, low wages, and staff shortages. Reports highlighted overreliance on trainees, leading to child abuse and harm incidents at childcare centres. In New South Wales, Affinity’s regulatory compliance issues were triple that of competitors, sparking concerns about declining standards post-acquisition. The scandal raised questions about Quadrant’s management priorities, emphasizing cost efficiencies over quality care.
