Which coalition backed an 80% tobacco excise cut?

The Coalition, led by Angus Taylor, backed the plan to cut Australia's tobacco excise by 80 per cent, a move that would knock roughly $30 off the price of a pack of cigarettes, taking prices back to around 2013 levels [1, 2, 4]. The policy has drawn comparisons to One Nation's earlier, smaller proposal to cut the excise by 75 per cent, with some accusing the Coalition of trying to outflank Pauline Hanson's party, though Taylor has denied simply copying that policy [2, 4].
