DIP Indicator Series - Definitions
The DIP Indicator Series is a national indicator that combines select elements of the IP Indicator with a daily indicator of product prices. Indicators in the DIP are provided for Unleaded Petrol (95 RON) and Australian Diesel (which contains a combination of gasoil and kerosene).

The IP element of the DIP indicator is based on data that is computed in strict conformity with the publicly documented computation procedures formerly adopted by the ACCC in its Intervention Price Series. The daily element of the DIP Indicator is derived from the same data source, but computing only a rolling single-day figure. The combination of the IP and daily indictors is graphed, providing a visual representation of the trend influence of daily changes in oil product prices on the 7-day rolling average IP price.

DIP Imported Product Prices
Product prices for the IP Indicator component of the DIP are based on a 7-working day rolling average of spot price assessments for the Singapore market, one day prior to the date of publication. The daily component is based on a single day, one day prior to publication.

DIP Exchange Rate (US$ / $A)
Exchange rates used for the DIP Indicator Series are the Reserve Bank $USD/$AUD exchange rates. The IP component uses a 7-working day rolling average. The daily component uses a single day, one day lagged. In the case of a public holiday in Singapore or Australia , during which daily quotation values are unobtainable, the DIP is not published on the following day as data for the daily component will be absent.

All other components
All other components of the DIP Indicator Series are described in the IP Indicator Series Definitions. This includes reference to International Shipping Costs, Federal Excise and GST.
