FRIENDS and family of 28-year-old Travis Davis are frantically seeking any information to help them locate him.
Travis went missing from Smithfield in Cairns and it's been six weeks since his mother, Sue-Anne Davis has spoken to her son.
She said up until then, Travis had been in regular contact.
"Then it just went quiet," she said.
"He'd been having a rough trot trying and couldn't find a job or somewhere to live."
Mrs Davis, who lives at Thangool, said when she last spoke to Travis on the phone, he had been living out of his car.
"A fellow from Papua New Guinea found him in the park and took him home.
"Travis said he was helping him out and he was doing some work around his place. From then on, we haven't been able to reach him.
"But we don't have a name. The police are trying to find out who he was," said Mrs Davis.
Since then, a couple of people have called to say they had seen Travis in his car.
"One woman said she was absolutely sure it was him because she noticed his hearing aid.
"That does and doesn't give us hope...why aren't people still seeing him," she said.
Travis is 172cm tall with fair hair and wears a hearing aid.
He drives a black Toyota low-lux ute, registration 953 SZT, with pink LKI sticker on the back window.
He may have a tan ridgeback cross pup with him.
Anyone with any information should contact Cairns police or call 1800 333 000.
