<P> The Australian Open is a major tennis tournament held annually over the last fortnight of January in Melbourne , Australia . First held in 1905 , the tournament is chronologically the first of the four Grand Slam tennis events of the year -- the other three being the French Open , Wimbledon and the US Open . It features men 's and women 's singles ; men 's , women 's and mixed doubles and junior 's championships ; as well as wheelchair , legends and exhibition events . Prior to 1988 the tournament had been played on grass courts , but since then two types of hardcourt surfaces have been used at Melbourne Park -- green coloured Rebound Ace up to 2007 and , afterwards , blue Plexicushion . </P>
