Six Australians have been charged over an international paedophile ring.
Federal police were alerted to the men after an investigation led by the London-based child exploitation and online protection centre.
The six men, from Victoria, South Australia and WA - aged between 28 and 60, were allegedly caught downloading photos of children.
Police seized computers and cds containing over two million child abuse images during the four month operation.
If found guilty, the men face a maximum of 10 years behind bars.
