"The whole response to the tsunami has been a reminder of the common humanity that we all share," Howard said.
"When you have tragedy, you forget differences of race, of religion, of ethnicity. The only aim you have is to deliver competent assistance."
Of the $8 billion in public and private pledges to nations hit by the December 26 tsunami, Australia's government promised $815 million, the largest amount from any country. Its military was among the first to respond with 1,000 Australian Defence Force personnel in Sumatra, along with helicopters, transport aircraft, a military field hospital and a water purification plant.
