"Modelling of higher tobacco taxes completed just five weeks ago by the independent Parliamentary Budget Office has placed a question mark over the Turnbull Government's budget-eve claim of a "black hole" in Labor's policy costings.
The Liberal Democratic Party asked the office to model an increase in the tobacco excise of 12.5 per cent over four years between 2017 and 2020 - similar to Labor's stated policy.

The costing for the Liberal Democrats, obtained by Fairfax Media, was delivered by the office on March 24 and used the most up-to-date tobacco consumption figures.
December's mid-year economic update contained a 3.8 per cent reduction in tobacco consumption.
The finding indicates that Treasury has identified a recent sharp declined in tobacco consumption in Australia." ...in the last 5 months ?

Dear oh dear. could be Morrison and the Libs up to their same old tricks when it comes to treasury matters, lying. Who would have thought.
