Federal Opposition Leader Bill Shorten is due to give his Budget Reply speech tonight, where he is expected to lay out an alternative vision for tax reform in Australia.

Labor has agreed to back the Government’s first set of tax cuts, focused on low and middle-income earners, but seems set to disagree on the second phase, which would put most Australian workers in the same tax bracket.

The Government could split their bill, in order to deliver on its promise of tax relief next July for low and middle-income earners, but Prime Minister Malcolm Turnbull, Treasurer Scott Morrison and Finance Minister Mathias Cormann all claim the bill can only be passed in its entirety.
