The 33-year-old Australian, starting from his third pole position, made the most of that advantage to hold his place in the crush on the opening lap, resisting all attacks at the first corner, and streaking clear of the field.
It was his first win since last year's Brazilian Grand Prix after he had become the first Australian victor since Alan Jones in 1981 when he claimed his maiden win in Germany - and will have injected priceless belief in his bid to challenge for the championship.
