In a commercial setting, parties agree to an access price for major capacity additions, to apply over the contract period. However, in the case of declared rail access in Queensland, the service is provided by a monopolist and the price of access is determined after long-term capacity contracts have been signed. Clearly it is easy for disputes to develop in such circumstances.
The QCA investigated options for pricing of access to major expansions in capacity for rail and port infrastructure. This included looking at where access to one tranche of capacity should be priced the same or differently to access to another. A Discussion Paper was published in April 2013.
