The Treasury Laws Amendment (Reducing Pressure on Housing Affordability Measures No. 1) Bill 2017 passed the Senate early last week. But as it was amended it needed to return to the House. The Government accepted the Liberal Democrat amendment – a review of the measures and some other changes – in a vote on the last sitting day of the year. The Bill, along with the First Home Super Saver Tax Bill 2017, now await Royal Assent.
