Thank you for the question.
In the first year, 2017-2018, the $30 million increase in revenue is the result of the immediate 2% increase in the excise duty.
In subsequent years, for the excise duty to keep pace with inflation, the forecast is to increase it on April 1 in each of the following years. Let us assume that inflation is at 2% next year. On April 1, 2018, therefore, there will be an increase, a readjustment of 2%. That is what explains the growth in additional revenue forecast for subsequent years.
If we compare that to what we are collecting at the moment, we see that, in the public accounts for the financial years that ended last March 31, the federal government took in about $1.6 billion dollars in excise duty.
