- Described in the Australian Dictionary of Biography: “Grey-haired and keen-eyed, with wild eye-brows and bristling moustache above an old-fashioned stovepipe collar, Nock was widely known to farmers (the ‘Cockies’ Patron Saint’) and sought out on agricultural issues. A vigorous and persistent advocate for rural interests, always well-armed with figures, Nock was an effective watchdog over various tariffs.”
