IPART's role in regulating rural and regional bus fares is to recommend to the Minister for Transport changes to the maximum fares bus operators can charge for regular passenger services for fare-paying passengers in rural and regional NSW. The Directory General of the Minister of Transport makes the final decision about the change in these fares. As in previous years, IPART conducted the review in line with the terms of reference provided by the Ministry of Transport, and used an industry-specific cost index known as the Bus Industry Cost Index (BICI) to guide its decision making on the require fare change.
