Our role

The QCA’s role as independent economic regulator

We are Queensland’s economic regulator. We prevent monopoly businesses from manipulating prices or terms in their market—and we do that by setting or monitoring prices, or through other arrangements. The businesses we regulate are in charge of vital infrastructure in Queensland, such as railways and ports, or they deliver essential services, such as water and energy.  Because of regulation, prices are competitive, and those who need to use infrastructure can do so fairly.

It is not always possible or sensible to have market competition in the provision of essential services where large scale infrastructure and therefore significant capital investment is required.

This is because there may be only one possible supplier (for example there may be only one possible site for a dam) or it may not be economic to have more than one supplier (for example, the costs of constructing a new electricity distribution system would simply outweigh the benefits).

In these circumstances, there may be limited, if any, competitive forces available to constrain the behaviour of businesses, especially in the provision of essential services such as water, energy and transport.

Our role is to put in place arrangements to prevent the abuse of market power that may arise from the lack of competition.
