Australian natural gas exports are expected to increase significantly as several large-scale projects begin production in the coming years. This is due to an investment of about $200 billion, equivalent to 12 per cent of Australia's annual GDP, which was largely in response to rising demand for natural gas that has gradually increased to account for about a quarter of global primary energy consumption worldwide.

In general, CNG price levels are determined by each country's fiscal policies and access to various sources of natural gas. Countries' policies on taxes, subsidies and energy preferences often have a much greater influence on tariffs than the cost of natural gas. Compressed natural gas prices vary widely from country to country and CNG retail tariffs in Australia are similar to those in other countries even though Australia is an exporting country.

As CNG is a relatively new fuel in Australia, the price of CNG in Australia varies greatly depending on whether it is purchased publicly at the filling station or for a private fleet

.

Historically, CNG prices have been stable in Australia allowing economic savings to transport companies that have used it as a fuel.
