While Wellington's problems are extreme, they are visible in towns across Australia, which has among the highest rates of methamphetamine use in the world. About 7 per cent of the population has used the drug, with more than 2 per cent having used it in the past year, compared with about 0.5 per cent in the United States and 1 per cent in Britain.
Authorities say the drug is largely manufactured in "meth labs" or imported from South East Asia and distributed by crime syndicates and outlaw biker gangs. Its low cost and increasing purity have left Australia in the grip of a devastating epidemic.
In recent months, two federal and state MPs have made emotional public appeals for help after revealing their own children were addicts. A federal "ice task force", set up in April, is due to present a plan next month for tackling the use and supply of the drug.
Some of the worst-hit communities have already begun to fight back.
The residents and police of Wellington have started a programme called "Dob in a Dealer", encouraging locals to give anonymous tip-offs to authorities. In just three months, the information has poured in and the programme has led to arrests of local dealers and a reduction in the availability of the drug.
Residents say the changes are noticeable: the firecrackers, which used to explode almost every night, now only go off once or twice a week.
"It was time for us to take our fate into our own hands," said Alison Conn, who runs a local community organisation.
"Dobbing in Australia is something we don't take to very kindly. But this has been impacting our families and our sisters and brothers. The dealers have quietened down. They know people are watching them."
