Another Senate Estimates session with the new Treasury Secretary and the evidence of Treasury politicisation mounts.

Under the Liberals, the Treasury spends more time costing and analysing Labor policies than comparable Government policies.

This became apparent when the Treasury confirmed that it hadnt done any analysis on what the impacts on house prices would be of APRAs macro prudential measures, enthusiastically cheered on by then Treasurer Scott Morrison.

JENNY MCALLISTER: Ms Quinn the modelling that was undertaken that you referred to, or the analysis. Did it indicate house price falls of 9 and 12 per cent in Melbourne and Sydney like we have seen over the last 12 months?

QUINN: So we werent looking specifically at house prices.

The Liberals had no modelling done by Treasury on falls in house prices resulting from regulator actions it had encouraged but there is no end to the amount of Treasury analysis or modelling commissioned by the Government on opposition policy.

Mr Gaetjens confirmed he would generally see the responses on analysis of tax reform policies mirroring Labor policies as they were sent to the Treasurers office.

In response to Senator McAllisters questions about whether there were any limits to Treasury being politicised via their analysis and modelling constantly ending up on the front page of The Australian newspaper, Mr Gaetjens said:

GAETJENS: We would try and do what the government has asked us to do.

Mr Gaetjens, who went from being Scott Morrisons Chief-of-staff to being appointed as Secretary of the Treasury, confirmed that he would be signing off on the independent Pre-election Economic and Fiscal Outlook during the election campaign as well as Labors Incoming Government Brief
