At first glance, Part 3–1 of the Fair Work Act 2009 (Cth) seems to overlap with long-established anti-discrimination laws, offering protection against adverse, attribute-based conduct in employment. On close analysis, however, it turns out to be a new and quite different regime. Although the Fair Work Act offers a simple alternative to dated and complicated anti-discrimination laws, its provisions are at times overly-simple, raising uncertainty about how they will operate. Our analysis leads us to conclude that the approach to discrimination protection in the Fair Work Act, while an important addition to the remedies available to Australian workers, is compromised by failing to take account of lessons learned in the long history of anti-discrimination law.
