"We've been litigating for a while and we've compiled a compelling case against both companies. For its own reasons, and it should be applauded, Diageo has decided to recognise its legal and moral responsibility to these people.''
"Grunenthal is a company that for 50 years has protested that the whole thalidomide disaster was an unavoidable, unpreventable tragedy ... it's a myth.
"Diageo has effectively picked up the tab for Grunenthal and it's now really up to Diageo whether it goes after Grunenthal for a contribution.''
The financial distributions would be based on the severity of victims' injuries, Mr Magazanik said.
The settlement would need to be approved by Melbourne's Supreme Court, which was expected to happen in February, he said.
"Everyone's confident that it will take effect.''
Diageo director Ian Wright said the company was pleased to be able to resolve the claims through an out of court process.
"We believe that the settlement reached today is both fair and equitable to all involved in this very sensitive and difficult situation.''
Papamoa-based thalidomide victim Terry Wiles said although he was not involved with the class action, the news was "really amazing''.
While it was good to see Diageo step forward and take responsibility, the lack of accountability from Grunenthal was appalling, he said.
"I think they have no conscience whatsoever. It was always about money and they just don't want to deal with it.''
Grunenthal needed to "own up'' and "show some moral fibre'', he said.
