Some of Sydney's most infamous Asian gangs have combined their powers to create a billion-dollar business empire in the illegal ice industry.

The gangs are moving away from street violence and are co-operating with each other to expand their business under the name The Company, which sees them import and produce vast quantities of the methamphetamine, the Daily Telegraph reports.

Organised Crime Squad Detective Superintendent Scott Cook said the members from gangs like Big Circle and Triads were so advanced they would be running multinational corporations if they were business people.

'Asian gangs are entirely transnational, they're nomadic and they do business how legitimate companies do,' he said.

One kilo of ice in Australia can fetch up to $2 million whereas the same volume would be sold for about $5,000 in China.

Det Supt Cook told the Telegraph several major drug operations, resulting in a number of arrests and hundreds of kilograms of drugs and drug precursors, had been linked back to the gang collective in the past two years.

The revelations of major gang connections to ice come after medical staff were given new guidelines for dealing with ice users in hospital emergency departments.

Some of the advice in the new guidelines includes ensuring medical staff use assessment rooms with more than two exits when examining ice users

Under the amended guidelines, emergency staff are directed to avoid prolonged eye contact and avoid sudden of threatening gestures. They should also ensure there at least two exits in an assessment room.

The guidelines follow horrific behaviour exhibited by people under the influence of the drug, according to the The Daily Telegraph.

Behaviour includes a young woman who chewed her toes off and a man who cut off his finger and refused to let medical staff re-attach it.

Another ice patient ran on the spot beside his bed for 24 hour before he finally collapsed.

NSW Police Commissioner Andrew Scipione has called for mandatory jail minimums for ice dealers and makers after linking the drug with this year's increase in nationwide domestic violence incidents.

The commissioner said last week he blamed ice for the weekly domestic violence report he's been receiving because of the nature of the crimes.

'In the past three or four days alone... we're talking everything from a lady who is heavily pregnant and gets savagely attacked, her throat cut and is deceased... a 12-year-old child beaten to death,' he told News Corp.

Mr Scipione said the ice suppliers are doing a lot of damage to society.

'This is a very serious situation and unfortunately we are going to continue to talk about it because there is no solution on the horizon,' he told 2GB radio.

The recent anti-ice advertisement from the government is graphic and is part of a campaign to raise awareness of the effects of the drug

Rural Health Minister Fiona Nash, who has been helping on a national taskforce into the drug, says it's a concerning link.

'It stands to reason that the abuse of the drug would lead to domestic violence,' she told ABC radio.

Senator Nash said the taskforce's report to inform the government's response to the ice scourge will be finalised in a matter of weeks.

It is expected to call for targeting addicts themselves with improved treatments, education and community support.

The minister said rehabilitation, education and support services were just as important as law enforcement.

Senator Nash touched on the harrowing stories she heard of Australians affected by the drug during taskforce consultations.

They include that of a bright young woman who turned to prostitution to fuel her habit, a mining executive whose life spiralled out of control, to a respected entrepreneur who went from riches to rags.

Mr Scipione is calling on the state governments to introduce harsher punishments for drug offences, including mandatory minimum sentences for both dealers and manufacturers of the drug.
