Syrah production. This made Shiraz the most planted variety in Australia and Australia the world's second largest Syrah/Shiraz grower, after France. Victorian regions include Heathcote, roughly 1.5 hours north of Melbourne. Cooler climate regions such as Western Australia's Margaret River produce Shiraz with marginally less alcohol content and often in a more traditional French style.
