Boxing Day this year will mark 20 years since the Indian Ocean Tsunami of 2004 which to this day is one of the worst natural disaster event to ever occur with over 227,000 people killed.

Australian forensic specialist Peter Baines was one of the people tasked with identifying the bodies of thousands of victims.

This experience inspired Peter to launch his own charity called Hands Across the Water which provides long-term support to children who were orphaned or displaced by the disaster.

This year Peter will be running 33 marathons in 26 days to hopefully raise $1 million for his charity.

Peter Baines told Peter Fegan on 4BC Breakfast, 'it's an important journey, we want to raise a million dollars.'

We want to raise awareness, we've raised $35 million,' he said.

'We have been and are the largest contributing Australian charity to Thailand. We've put 40 kids through university.

We're building an agricultural learning centre, a hospitality learning centre,' Baines said.

'But, we're basically unknown in Thailand, all of that $35 million has basically come from Australia and hopefully the run will change that.'
