Energy companies should look to source gas on international markets to fulfil their commitments to international customers - or be forced to do so - to help solve the national supply crisis, says the head of one of Australia's biggest manufacturers.

In the latest plea from a senior manufacturing leader to address spiralling gas prices, Orica chief executive Alberto Calderon said on Thursday the current "ridiculous" situation represented a "crisis point".

Mr Calderon said Orica was an energy-intensive business and had faced exponential increases in energy costs that meant prices in Australia were more than double of what was being paid in China or Japan.

"What is happening today is myopic and unsustainable, cornering domestic markets with prices so much higher than the international prices will eventually lead to a bad outcome, price ceilings or other non-market measures," said Mr Calderon, a former chief commercial officer at BHP.
