"The water police sent us a video and she looked in good condition," she said.
They immediately booked flights on their credit card.
However, by the time they reached the wrecked vessel in Australia, thieves had totally ransacked the yacht.
"We were left in a Catch 22 situation where we were no longer able to salvage her free of charge," she said.
The salvage company would initially have taken the boat for nothing and recouped its money from the valuables on board.
"A brand new 200kg anchor and chain, winches, lines, the stove ... everything; you name it it's gone," she said.
It was now a wrecked shell and would cost $20,000 to have removed.
"We put our hands up to the water police, the national park and marine authorities and told them there was nothing we could do," she said.
The couple had no insurance but Davies said insurance for international sailors was "nigh-on impossible" to get.
The cost of salvage was escalating and the national park ranger had told them the boat was being broken up by waves.
"We wanted to do the right thing and get her off the beach for conservation reasons but the opportunity to help has been taken from us."
She feared the authorities would remove the boat and send the bill to the couple.
"We have lost all our possessions, our home and we have no money. We are still getting over the emotional trauma of that. We have pleaded for help."
They were staying with Davies' relatives in Queensland but hoped to return to New Zealand for jobs.
