"He was in Brisbane and his phone had gone flat - so no one had been able to get a hold of him."
According to Palmer's mother, Roach had been with a friend the evening he disappeared. He had gone to tell his partner he might have a drink with a friend he had met on their holiday, but this didn't end up happening.
The friend he was with thought he had gone back to his room, but he didn't return.
"They had been to Sea World that day," Roach said.
"Mum said the holiday was going perfectly - there were no arguments or anything."
Palmer said they had planned on going to Movie World the day after he disappeared. Roach had been telling his stepson how excited he was to tick it off the list of theme parks.
The family had worked with one of Roach's cousins, who lived in the area, over the weekend to put out flyers and co-ordinate their own search.
