"In April 2015, measures to create budgetary savings
by increasing the pursuit of outstanding debts and
investigation of cases of fraud in the Australian welfare
system were first flagged by the Minister of Social Services
Scott Morrison and the Minister for Human Services Marise
Payne and formally announced by the Abbott government in the
2015 Federal Budget."

Paul,

The ICAC should also investigate the 1200 people that Labor forced to drown and the imprisoning of 1000s of children.

Foxy,

According to YOUR link:

"The Robodebt scheme was .....Put in place in July 2016 and announced to the public in December of the same year,"

No connection to Morrison.

In the link I gave regarding the Robotdebt Scheme
under the heading of - "Creation and Announcement"
It quite clearly states the connection of Scott
Morrison to the scheme. And the Abbott government's
announcement of it in their 2015 federal budget.

We don't know the extent of Scotty's early involvement – the information isn't publicly available yet.
But what we can say with certainty is that he wan't entirely to blame. Whether or not it was originally his fault, his successors were negligent.

Maybe Morrison's 'Minister for Scams' Stewart Roberts can shed some light on the subject, he's not saying a lot about his involvement in "Greywolf Investments" which resulted in battlers being taken for a financial ride. This has been exposed by the ABC's 4-Corners program. More to come I'm sure, where is that Federal ICAC when you need it.
