A Gold Coast man who has admitted stabbing his father to death on a houseboat had long held an intention to hill him, the Supreme Court heard.

A Gold Coast man who allegedly killed his father for financial gain thought about doing it his whole life, a court has heard.

Nikolaus Blyton is accused of murdering his 66-year-old father Ron Livingstone by stabbing the pensioner to death on his houseboat at Hope Island.

Mr Livingstone’s disappearance in November 2011 wasn’t noticed until a tip-off to police last June.

Blyton, then 22, and alleged accomplice Timothy Cairns were arrested shortly after.

Blyton’s bail application on Thursday said he admitted to undercover police after his arrest that he’d stabbed his father to death and disposed of his body.

“The confessions to undercover operatives illustrate an intention to kill and that he thought about it his whole life,” crown prosecutor Amanda Robinson told the Supreme Court in Brisbane.

“He admitted to calling the deceased out of bed and then stabbing him on multiple occasions, which is consistent with the forensic evidence.

“He said all was calm beforehand and that was not consistent with illustrating a case of self-defence.”

Remains believed to be Mr Livingstone’s were later found in bushland at Coomera, the suburb next to Hope Island.

Blyton is charged with murder and interfering with a corpse and Cairns with being an accessory to murder after the fact, interfering with a corpse, attempting to pervert the course of justice and stealing.

Blyton’s barrister Bruce Walmsley said his client did not contest that he killed his father, but indicated he would claim self defence.

Mr Walmsley said the fact Blyton went about his business for 18 months after his father’s death helped show he wasn’t a flight risk.

But Justice Martin Daubney refused bail, saying the evidence from undercover police supported the Crown’s case.
