Section 230(1)(a) and (b) of the Liquor Act 1992 (Qld) provide alternative defences: a defendant may rely on an honest and reasonable belief that a person was 18 without having sighted proof of age. Section 230(2) creates a rebuttable evidentiary provision — failure to request proof of age is evidence of unreasonableness but can be displaced by other evidence such as the defendant's prior familiarity with the person and their appearance. The defence is not limited to cases where proof of age was requested or sighted.
