The Sydney Morning Herald''s Debi Enker wrote "Significant Others is a Trojan horse of a show. It's an effective crime drama that does pretty much all you could ask of it. But lurking inside there's a whole legion of more challenging ideas."[2] Luke Buckmaster of The Guardian gave it 4 stars, concluding "The show's final revelations and moments of catharsis are a little neat, wrapping things up decisively, but this is a class act from beginning to end."[3]
