At one Salvo's store there is so much rubbish being dumped, it's spread to a neighbouring piece of vacant land. What looks like a tip is actually part of an epidemic sweeping the country.
According to charities the holiday period is renowned as dumping season.
The amount of junk dumped at the Salvo's store in Melbourne's western suburb of Deer Park got so bad, they had to install a fence at a cost of $10,000.More stories from Today Tonight
Now the empty lot next door is littered with soiled mattresses, smashed TVs, dirty couches and other dangerous goods.
According to sustainability manager Donald Munro, illegal dumping costs the Salvation Army $5 million every year across the country.
"We're spending about $1.8 million annually on rubbish removal, and at that site at Deer Park the monthly bill is about $5000," Munro said.
According to the founder of Clean Up Australia Day Ian Keirnan, illegal dumping has become an epidemic.
"We know that rubbish attracts rubbish. If I go and dump a mattress and a pile of garbage here, I can come back tomorrow and the site will be twice as big, because rubbish attracts rubbish," he said.
In the battle against illegal dumpers, many charity stores have gone high-tech, installing cameras in an attempt to catch offenders dumping or stealing donated goods.
