As the government considers a tax reform agenda without changing the GST, Assistant Treasurer Kelly O'Dwyer discusses tax and superannuation with Michelle Grattan – and strongly defends the Business Council of Australia’s Jennifer Westacott against an attack by Victorian Liberal president Michael Kroger.

O’Dwyer also suggests the Liberal Party tap talented women on the shoulder to get more female representation in parliament.

Michelle Grattan does not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and has disclosed no relevant affiliations beyond the academic appointment above.
