Mumbai:The countdown to the October 6 four-Test India-Australia series has begun with two members of the Australian team arriving in Mumbai earlier on Friday. Justin Langer and Nathan Hauritz who were not part of the Australian team in the Champions trophy were the first to arrive. Shane Warne and Cameron White, who missed the connecting flight from Singapore, are scheduled to reach later. The rest of the team will get in on Saturday morning from England minus Ricky Ponting who will miss atleast the first test because of a fractured finger. Wicketkeeper-batsman Adam Gilchrist will captain the team while Brad Hodge is taken in as Ponting's replacement. The world champions play Mumbai in a 3-day game starting on the 30th of September. Settling scores Australia's Test opener Justin Langer described touring India as the "ultimate test". He believes that victory in India will complete the set as far as his generation of cricketers is concerned. He added that the Austalians enjoyed playing in India. India took possession of the Border-Gavaskar Trophy thanks to an epic 2-1 series win in 2000-01, and Australia were unable to wrest it from their grasp during last year's 1-1 draw in Australia. The rest of the team arrives in India in the early hours of Saturday morning from England, where they lost to England in the semi-finals of the ICC Champion's Trophy. The team will meet the press on Saturday afternoon.
