My question is to the Minister representing the Prime Minister, Senator Brandis. I refer to the leader of the Western Australian Nationals Party, Minister Grylls, who is advocating for an increase in the resources production rental fee from 25c a tonne to $5 a tonne, which is estimated to raise $1½ billion a year. My question, Minister, is very, very simple: does the government support Minister Grylls's plan?
