Queensland Police haven't found any evidence suggesting third party involvement in the case of a New Zealand man who was found under an Australian railbridge with serious injuries.

This contradicts claims by the 25-year-old man's husband that he was attacked and then "thrown off" the bridge in Gladstone, Queensland by a married man in a "gay hate crime".

Maioha Tokotaua, 33, found his "mangled" husband, Joth Wilson, originally of Palmerston North, unconscious about 2am on New Year's Day.

As well as broken bones and burns to 40 per cent of his body, Wilson had a brain haemorrhage and a severed spinal cord - making him unlikely to ever walk again, theDaily Mail reports. Wilson remains on life support.

A distraught Tokotaua told Daily Mail Australia he believed his husband was attacked after a married man who propositioned him started to fear he might tell his family about his advances.

He also claims Wilson's burns appeared to have come from a chemical or lighter fluid which was poured on him and set alight.

But Queensland Police say they have not located any evidence to suggest another person was involved in the incident, which they described as a "fall".

They also say Wilson's burns might have come from a power line above the train tracks, and his other injuries were as a result of the fall.

Tokotaua, who has been keeping a vigil at Wilson's bedside for the past five days, said: "There were these guys who had been harassing us for some time after one of them, who is married with children, made an advance that Joth rejected.

"There's no money involved, no drugs, no debt, there's just no motive for the attack other than they were intimidated that we might tell their families.

"It was a gay hate crime."

The couple, who had been visiting family and travelling along Australia's east coast, have been married for three years, tying the knot after gay marriage was made legal in New Zealand.

They have three adopted children and have also helped to raise a total of 15 foster children, Tokotaua said.

The pair, from Taranaki, would have been heading home next week to be with their children if it was not for the incident.

Police have been unable to formally interview Wilson due to his injuries. Their investigation into the incident is continuing.
