The MMA study focused on the three main components of the import parity price (IPP) for regular unleaded petrol, premium unleaded petrol and diesel—namely, the refined fuel benchmark, the fuel quality premium and freight.
In August 2006 the Treasurer asked the ACCC to provide quarterly reports on the differential between E10 and unleaded petrol prices. The ACCC provided four reports on a quarterly basis until September 2007.
In early March 2001 the government asked the ACCC to examine the feasibility of placing limitations on petrol and diesel retail price fluctuations throughout Australia.
