The former Coalition government lacked “empathy” for welfare recipients and were more focused on “cost savings” than problem solving, a former senior public servant has told the Robodebt royal commission.

Ex-Department of Social Services (DSS) deputy secretary Serena Wilson returned to the stand in Brisbane today, giving damning testimony of eroded relationships between senior heads of departments responsible for rolling out the unlawful debt-raising scheme.

She also detailed “disinterested” ministerial office staff, who she believed focused only on cost savings.

In a statement to the royal commission, Ms Wilson described the office of then-social services minister Scott Morrison as having “limited interest in advice from DSS” and being more concerned with costing data during the period between 2014 and 2018.

“My recollection was that it was rare that work in this period started with a discussion about the problem that the government was seeking to address,”  Ms Wilson said in her statement to the inquiry.

“Instead proposals were directed at finding cost savings.”

When asked to explain her position further by senior counsel assisting the inquiry Justin Greggery KC, the former high-ranking public servant said she believed the minister’s office did not look for the merits of different strategies relating to social security but “on occasions appeared to be looking for a problem”.

Damning observations of the then Coalition governments attitude to social security were also revealed by Ms Wilson’s statement, shown today to the inquiry.

“The Coalition government took a different attitude to the social security system, or as they preferred to call it, the ‘welfare’ system, from the previous government,” the statement read.

“They had a strong view of ‘deserving’ and ‘undeserving poor’.

“From the 2014 budget through to the 2018 budget, the vast majority of my work involved identifying saving options to cut social security expenditure.

“I had built a career trying to improve lifetime wellbeing and address the needs of disadvantages people, but [in my opinion] there was little empathy for, or understanding of those needs within the Coalition government and ministerial staff.”

When asked to elaborate, Ms Wilson told the royal commission she believed the then Coalition government had a “very pejorative view of jobless people”.

Internal complaints ‘fraught’ in public service

Ms Wilson later did not hold back about the fractured and dysfunctional working relationship between herself and her counterpart at the Department of Human Services, Malisa Golightly.

Ms Golightly has since died.

“In terms of our working relationship … it wasn’t collegiate and on a number of occasions I felt quite pushed by her or would experience push back by her,” Ms Wilson said.

She explained said she had worked with Ms Golightly at another government department in 2005 and the pair had a “very unhappy relationship”.

“I did not pursue bulling claims against her,” she said, adding that making formal complaints could be a “very fraught areas in the Australian public service”.

Wilson ‘didn’t read’ note on income averaging

Much of Ms Wilson’s time on the stand centred around the assertion she had communicated concerns to DHS bureaucrats about the scheme that later became Robodebt.

She recalled conversations with Ms Golightly where she said she raised concerns about income averaging but had no memory of an executive ministerial minute that explained the policy would roll out with income averaging at its core.

“I didn’t have a lot of knowledge about the proposed implementation, but I believed DHS had understood the concerns raised and that they accepted our position and that they would change and intended to change their approach,” Ms Wilson said.
