WA gas giant Woodside says if the eastern states want gas, they can come and get it.

As the gas supply debate continues, Woodside says it has gas available, but it will be charging commercial prices.

“We've already spoken to one or two of the projects on the east coast around gas swaps or cargo swaps, so they're aware of the pricing structure,” Woodside chief executive Peter Coleman said at the company’s AGM in Perth.

“They're aware of the availability of that, and they just haven't prevailed themselves of that at the moment.

“This debate around; ‘Is it available, yes or no? Can I get it at spot prices, yes or no?’. The answer is yes, and it's always been yes,” Mr Coleman said.

“We've got cargoes available to sell in spot prices. If you wish to purchase them, then come and see Woodside.”

Meanwhile, WA Premier Mark McGowan has raised the possibility of building a cross-country pipeline in exchange for a better share of GST.

“They have a severe gas shortage over east because of policy failures on their behalf that we've avoided with [former premier] Alan Carpenter's gas reservation program,” Mr McGowan said last week.

“If [they] want to take our gas ... they have to provide a better deal to Western Australia when it comes to the GST.”

Mr Coleman says a pipeline will not solve the immediate shortage crisis engulfing the east coast.

“They have two different timeframes,” Mr Coleman said.

“The pipeline, realistically, has a minimum of five years — absolutely minimum of five years, more likely 10 years — before you would see any gas coming through a pipeline.

“Regasification has the advantage of it can really be put in place with a 12 months lead time, for example.”
