'With time,' writes Australian Rules Football goal umpire Chelsea Roffey, 'I wrapped my lady brain around the mathematics of scoring.' Roffey's account of being an élite football official doubles as a sharply funny take on the progress the AFL community has – and hasn't – made in its approach to gender. Employing a sequence of well-aimed one-liners, Roffey gets the sarcasm level just right, a deceptively tricky feat. But she does more than chase laughs, by offering a penetrating personal account of her push into a traditionally male domain; she also makes pertinent and expert observations about the game and its curiosities, including that television commentators 'have a surprising level of influence on the public's critical-thinking ability'.
