My question is also to the Treasurer. Is the Treasurer aware that, between the election and last Saturday, the average price of petrol has increased by 4c a litre in Sydney, 4.8c a litre in Melbourne, 4.9c a litre in Brisbane and 7.1c a litre in Adelaide? Will the Treasurer advise the House what flow-on impact this petrol increase, along with the new tax on diesel for trucks, will have on grocery prices?
