'Australia's dumbest criminal' faces sentencing for crashing into cop car with ...

'Hopeless, negligent and shambolic' - that's how a lawyer has described the crimes of a hapless drug courier sprung trafficking $200 million in meth because he crashed into parked police cars.

Simon Tu, 28, was branded 'Australia's dumbest criminal' when he accidentally ploughed his white Toyota HiAce into stationary cop cars in Sydney's Eastwood one Monday morning last July.  

Tu was ambling down the road, past the police station on Ethel Street, when he accidentally slammed into two parked NSW Police cars.

But he kept driving until officers spotted his van an hour later.

Tu later said he had suffered a 'microsleep' and made the farcical claim he was delivering 'food around Sydney' - rather than 260kg of crystal methamphetamine. 

That humiliating moment brought him in front of a NSW District Court Judge Penelope Hock on Thursday for a sentencing hearing.

As Tu, dressed in prison greens, watched via video-link from a prison on the NSW mid-north coast, his lawyer Phillip Boulten SC argued his crime was at the lower end of commercial drug supply offending. 

He was a simple courier, he said - although not a very good one. 

'His driving is what gave it away, and his role was to drive,' lawyer Phillip Boulten SC told the court. 

'In some senses it was a hopeless execution of the task he was asked to perform,' he said, going on to describe it was 'shambolic' and 'negligent'.

Tu bowed his head and appeared to inspect the back of his hands as the barrister delivered his withering assessment.  

Judge Hock told Mr Boulten: 'I accept that submission. Shambolic is a good word.' 

Tu has never given a full explanation for how he obtained the drugs or the mysterious criminal syndicate involved.

He only gave police the barest of explanations at the time of his arrest, according to an agreed statement of facts.

Police noted he was 'fidgety' when pulled over and did not believe his claims he was delivering food.

As officers opened up the cardboard boxes loaded into the back, one policeman told Tu: 'Someone isn't going to be happy. You know how much it's worth?'

'A lot,' Tu admitted. 

'What's the go, you owe people money or just wanted to make some quick cash?'

'Something like that,' Tu said. 

Officers found a note in his pocket saying 'Pizza Hut, Eastwood' - where he had apparently picked up the drugs. 

It was not clear whether he had collected the drugs before colliding with the police vehicles, or had done so in the hour before he was sprung, the court heard. 

Mr Boulten did shed some light into why Tu had become a drug trafficker in the first place, saying he was a drug-user and both he and his business had financial difficulties. 

'He was using cocaine, he was gambling,' Mr Boulten told the court, adding he clearly had owed someone money. 

Tu pleaded guilty to a large commercial drug supply charge earlier this year and faces a maximum sentence of up to 20 years' imprisonment. 

Judge Hock will deliver her sentence on Friday. 

BLOW-BY-BLOW: HOW SIMON TU WAS SPRUNG, ACCORDING TO COURT FACTS

After crashing his car into the police vehicles at 10.36am on July 22, Tu drove his banged-up van for about an hour before officers pulled him over on Blaxland Road, Ryde, the court document said.

Tu, dressed in a white business shirt, jeans and loafers, was 'nervous, shaking, fidgety' and avoided eye contact as officers asked what happened outside the police station. 

Tu said he had fallen asleep behind the wheel - veering onto the wrong side of the road - and only woke up when he rammed into the cop car. 

'Driving and microsleep ... realised I fell asleep,' he said. 

Tu, who was being recorded by police body worn cameras, was then asked what he'd been doing in the suburb, the court facts said.

Someone isn't going to be happy. You know how much it's worth?
