An ex-bikie who shot to notoriety after posting a video with NRL star Jarryd Hayne has been jailed for four years after threatening to kill a man over a $16,000 drug debt.

Former Hell's Angel Christopher Bloomfield pleaded guilty to extortion, assault, stealing and making threats to kill after bashing and extorting two other men involved in a drug deal.

Bloomfield made national headlines in 2016 when he appeared in a controversial Snapchat video with Jarryd Hayne waving a wad of cash and saying: 'Sweet. Haynesy just gave me five grand.'

Hayne later denied knowing who Bloomfield but was warned against associating with criminals by the NRL, which cleared him of wrongdoing.

The court also fellow bikie Rhys Mirki had attempted to extort money out of a man in 2014.

It was found a drug user had failed to pay a $16,000 debt for at least an ounce of methamphetamine provided by the pair.

Prosecutors are unsure how much methamphetamine Bloomfield and Mirkin supplied but estimate it was an ounce, leaving their victims with a $16,000 debt after the deal in late 2013.

Over the next six months, they pursued the man Mirkin had sold the drugs to, with Bloomfield acting as an enforcer trying to recoup the debt, Brisbane Supreme Court heard.

Bloomfield, a former under 20s Gold Coast Titans junior, bashed the man in a park, punching him several times before pulling a knife and cutting his victim's hand.

'You got carried away while trying to enforce the drug debt for Mirkin,' Justice Debra Mullins said.

When the man the drugs were sold to didn't pay, Bloomfield turned on another man who had introduced them and said the debt was now his responsibility.

One way Bloomfield tried to encourage repayment was by taking the second man's BMW convertible and using it for four weeks.

He gave it back to the man so he could have it serviced but then reclaimed it for another two weeks, Justice Mullins said.

Bloomfield's next move was to text the man in January 2014, warning him off contacting police and saying that he knew where his family lived.

The content of the chilling text messages were revealed by 9News, which read: '...U wanna go to the cops I know where your f***ing family lives and I'll shoot every single one of those motherf***ers til I find you!!'

'You said that you would shoot every single one of them until you found him,' Justice Mullins said.

Months later, Bloomfield went to the man's home and punched him in the mouth.

Both Bloomfield and Mirkin nodded as Justice Mullins said they now regretted their previous associations and the period of life during which they offended.

Bloomfield was sentenced to four years and three months jail, but will be eligible for parole after serving 11 months.
