Australia's tour of India will go ahead as planned despite a spate of recent bombings, although Cricket Australia (CA) say security around the team will be stepped up.

The four-Test tour had been in doubt after a series of bombs in New Delhi at the weekend which killed at least 20 and injured more than 90 others. But CA are satisfied the safety arrangements put in place are adequate and the players and support staff will leave for India as scheduled on September 21.

"Our advice is there are some concerns and to exercise caution, but currently they do not compromise the tour," Peter Young, a spokesman for CA, said.

Tight security arrangements are in place for the Australia A team now in India and will also be arranged for the Australia team for the four-Test tour, which includes a Test match in New Delhi starting on 29 October.

"In consultation with the BCCI, we have upgraded security in and around the dressing rooms and they will have an escort to the ground," Young said. "Australia A players have also been told not to leave the hotel without good reason. It's just a matter of prudence."
