Once or twice a week in the New South Wales town of Wellington, a burst of firecrackers goes off late at night to deliver a message that the residents have long since learnt to recognise: a local drug dealer has taken delivery of a fresh supply of crystal methamphetamine.
The fireworks are just one of many unwelcome recent developments in this town of 4500 people, which has been so overrun by crystal meth, or "ice", that it has become known as "Little Antarctica".
Police Inspector Scott Tanner, who works in Wellington, said children as young as 10 have been experimenting with the drug, a highly addictive euphoria-inducing stimulant made notorious by the TV series Breaking Bad.
Having observed close-up the "insane strength" of those high on ice, he says it has left people "scared of their kids and grandkids".
"It is so cheap, so easy to get hold of," he said. "It is as little as A$20 ($21.80) a hit - cheaper than a carton of beer. We got called to a domestic situation last week. A large individual had been on an ice binge. It took five policemen to hold him down. He managed to bend the handcuffs. In 23 years of policing I have never seen that."
