Career
Born in Sydney, he was a wholesaler and exporter before entering politics. In 1975, he was elected to the Australian House of Representatives as the Liberal member for Brisbane, defeating Labor Member of Parliament Manfred Cross amid the massive Coalition landslide that year. A redistribution ahead of the 1977 election technically made Brisbane a safe Liberal seat, but Johnson narrowly saw off a spirited challenge from Cross that year.
He held the seat until his defeat by Cross in 1980.
