floydbloke:Bordering on politics, the GST take on petrol per day is approx. $1million more than it was a year ago.
(Calculated as follows, petrol price $1 more per litre, annual petrol sales of 3.2 billion litres per year [source: comcom], arbitrary deduction by me of 20% for commercial sales, = 7 miilion litres of retail petrol sales per day.)
Assuming sales volumes are the same. If sales drop, so does the tax revenue.
