Disease outbreak the next challenge for Samoa
The Red Cross says the initial response has focused on providing medical assistance and emergency shelter but now needs to shift to rebuilding infrastructure for water and sanitation.
Samoa's National Disaster Council says the cost of infrastructure damage from the tsunamis is expected to exceed $41 million.
Rescue operations in the Pacific have now turned to grim recovery efforts in the wake of Wednesday's devastating tsunami. The death toll on Samoa, American Samoa and Tonga is over 150 and there are fears for scores more people on outlying islands.
Inside Apia Hospital, people are battered, bruised and traumatised beyond belief and locals cover their noses against the smell.
Hugh Grantham from the Australian Relief Team says Australian doctors are among those trying to stop the spread of disease.
"The injuries are those that you tend to get with a tsunami, which are cuts that then get infected because the sand gets into the wound, and unless we get it out, it gets infected," he said.
Outside, the search for bodies continues. Emergency workers have given up hope of finding any more survivors.
Samoan Resident Angi Wetzell says she has seen bodies of those who did not make it.
"It wasn't a shock to see a dead body, but probably the state of the bodies is what's more shocking," she said.
Officials fear whole towns have been destroyed on outlying islands and hundreds of people remain missing. Aid is coming in from Australia, New Zealand and the United States.
The devastation on Tonga is only just being made apparent. At least nine people are dead but authorities have had difficulty getting to affected areas.
Dozens of aftershocks have been rocking the region since Wednesday's tsunami-generating quake.
Yesterday afternoon, the most powerful yet, an offshore 6.3-magnitude quake, rattled the nerves of everyone in Samoa.
The last injured Australian survivor has arrived back at Richmond air base in Sydney.
School teacher Claire Rowlands from Smeaton in Victoria lost her travelling companion and best friend, Ballarat woman Vivien Hodgins, in the giant wave.
Ms Rowlands was too injured to be flown out with the rest of the Australian victims, including Tasmanian horse trainer John Blacker, whose wife Marie was ripped from his arms and swept away.
For the six Australians, this has been a holiday of heartbreak.
They were flown to Brisbane, where they were recovering in hospital and two have now been released.
New Zealander Malcolm Lawrence says he met Vivien Hodgins the night before she died.
"She was just a lovely, vivacious person. She was just so bubbly," he said.
Mr Lawrence says he cannot get the image of the wave out of his head.
"A Samoan boy came running through... further up and just yelled at us to run, get out. And we looked around and the tsunami, the water was coming over the reef," he said.
This village of Lalomanu is where most of the Australians died, including a 15-month-old Australian boy.
Locals are braving the putrid smell, using bulldozers and their bare hands to pull out more bodies.
Stunned survivors are now living in makeshift hillside camps and are picking through the rubble for anything usable.
There is talk that all Samoan victims will be buried in a mass grave. Last night 13 members of the same family are being buried together a mass grave.
