After raising millions for cancer research, Samuel Johnson has taken aim at the way donations are collected on the street - revealing that most of the money pledged doesn't make it to the cause.
'Chuggers', or collectors who hassle passers-by for charity money on the street, typically work by signing people up for donations.
However, it turns out that the first year of the charity subscription covers commissions, meaning that the actual charity doesn't receive any money until 12 months after the donator signed up.
“Chuggers are slugs, they’re dogs,” Johnson, 40, told the TODAY Show.
“I’ve really got no time for them to be honest. They’re snakes. Sharks.
"They’re not doing anything illegal but if you’re not prudent about how you give, if you don’t know about the organisation you’re giving to, then I’d be pretty cynical about how much is ending up at the cause."
Charities often employ chuggers, or 'charity muggers' due to staff shortages meaning they are unable to raise funds themselves.
A third party then takes to the streets to get people to ink on for monthly donations.
The Australian Competition and Consumer Commission released a report on this last year.
Trends show that most Australians opt out of monthly donations after just over six months, meaning that the charity doesn't see any of the money donated.
