Thank you for your email of 21 May 2008 to the Australian Competition & Consumer Commission (the ACCC) regarding the price of diesel fuel. I understand from your complaint that you are now paying $182.5 per litre for diesel and that there has been a 33 cent rise in Melbourne in the last three weeks
The role of the ACCC is to ensure compliance with the Trade Practices Act 1974 (TPA), which is designed to encourage fair trading and discourage anti-competitive conduct through a specific set of competition and consumer protection rules.
Prior to 1 August 1998 the ACCC endorsed the maximum wholesale prices for petrol and diesel of the oil majors and established freight differentials. On that day petrol and diesel prices were deregulated and wholesalers are now free to set their own prices based on market conditions.
The benchmark for diesel is the spot price of Singapore Gasoil (with 50 parts per million sulphur content). There is generally a time lag of around one to two weeks between changes in international prices and changes in retail prices, due to the averaging formula used by refiners in Australia when setting their wholesale prices. This lag may be longer in country areas because fuel stocks are replenished less frequently by wholesalers and retailers in the country due to the lower volume of sales.
This benchmark has recently hit all time high levels, as a result of increased international demand. A significant factor contributing to diesel prices being higher than petrol prices in Australia in recent months is that the international benchmark price for diesel has increased relative to the international benchmark price for petrol. Over the period January 2008 to late April 2008 the price of Singapore Gasoil has been around US$15 per barrel (or Australian 11 cents per litre) higher than the price of Singapore Mogas 95 Unleaded.
Petrol prices in the major metropolitan areas and locations close to them tend to move in cycles. In the case of diesel there are generally no price cycles. This may be because a large proportion of diesel sales are on a contractual basis and therefore not at the pump price.
Further information on this topic can be obtained from the ACCC booklet, Understanding petrol pricing in Australia, which is available through the following link:

In response to the increased rise in fuel and diesel prices the Assistant Treasurer and Minister for Competition and Consumer Affairs, the Hon Chris Bowen MP, announced Mr Pat Walker as the Government’s nominee for the new Petrol Commissioner. He also announced that he was asking the ACCC and the new commissioner to commence a renewed focus on LPG and diesel prices. As part of this monitoring, the ACCC closely monitors petrol and diesel prices in all capital cities and around 110 country towns. In addition, the ACCC follows developments in the petroleum industry and will enforce the provisions of the Act if there is evidence that it has been breached.
Additionally, On 15 April 2008 the Government announced the establishment of a National FuelWatch Scheme to promote competition and transparency in the petrol, diesel and LPG markets. The scheme will commence on 15 December and the ACCC is working on the implementation of the scheme.
Thank you for contacting the ACCC and I hope this information is of assistance.
Yours sincerely,
