Watt’s approval ends years of uncertainty over the future of the North West Shelf, which has been supplying gas to WA customers and shipping super-chilled liquefied natural gas cargoes to Asia since the 1980s. Its approvals were due to expire in 2030.

Woodside on Friday welcomed the government’s extension decision, noting it came with “rigorous conditions” to protect cultural heritage.

“This final approval provides certainty for the ongoing operation of the North West Shelf project so it can continue to provide reliable energy supplies as it has for more than 40 years,” Woodside chief operating officer Liz Westcott said.

“Woodside remains committed to protecting the Murujuga Cultural Landscape and was a proud supporter of the World Heritage nomination and assessment process.”

Australian Conservation Foundation climate program manager Gavan McFadzean said the government’s progress on renewable energy was “wiped out” by its support for fossil fuel expansion.

“The conditions can’t alter the fact the Albanese government is responsible for granting one of the world’s largest gas approvals while the planet is engulfed in a climate crisis,” McFadzean said.

“It beggars belief that the Albanese government would choose to detonate this carbon bomb. With this decision, Prime Minister [Anthony] Albanese has betrayed Australians who voted for him, believing he was serious about acting on climate change.”

Woodside’s Karratha gas processing plant is less than one kilometre away from the World Heritage-listed Aboriginal rock art, known locally as Murujuga and up to 60,000 years old.

A departmental briefing prepared for Watt and released under freedom of information laws warned that if the extension was granted, emissions from the Karratha plant could affect the ancient rock art and heritage values of the Dampier Archipelago, including Murujuga.

Traditional Custodian Raelene Cooper applied to the government for a cultural heritage assessment of Murujuga under section 10 of the Aboriginal and Torres Strait Islander Heritage Protection Act. The Federal Court in August ruled the federal government had unreasonably delayed its response to her application.

Section 10 of the act allows the environment minister to preserve culturally significant sites and to stop any works that could “desecrate” those sites, and Cooper claimed Woodside’s emissions were accelerating the degradation of the rock art.

“This decision is a slap in the face. It allows Woodside to continue operations and pollution to 2070. It is a crime against Murujuga and a crime against humanity,” Cooper said.

Watt said he had made a partial declaration to protect Murujuga’s heritage value, but that the declaration would not prevent industry from operating in the area.

This, he said, would protect “a significant Aboriginal heritage area and/or objects that are under threat of injury or desecration”.

“The declaration will mean additional legal protections placed over part of the area, to ensure Murujuga’s ancient rock art is appropriately protected into the future,” Watt said.

“Importantly, this decision does not stop industry from operating at Murujuga.”

Energy industry leaders on Friday said the announcement would drive investment and ensure Australia had enough gas to back up the accelerating role of renewable energy.

Anita Logiudice, the policy and advocacy director at the Chamber of Minerals and Energy WA, said the long-awaited resolution significantly boosted the state’s energy security and would benefit West Australian industry and households.

“The importance of the North West Shelf to WA cannot be overstated,” Logiudice said.

Watt gave preliminary approval in May to the 40-year expansion of Woodside Energy’s operations in the north-west of WA, comprising a vast network of offshore oil and gas infrastructure and the onshore gas-processing hub in Karratha.

“If Australia truly wants to partner with the Pacific for COP31, it must prove it with a genuine and strong climate plan,” Varea said.

“That plan must align with keeping warming to 1.5 [degrees] and stop new fossil fuel expansion.”

“It would show that ‘hosting with the Pacific’ is a slogan, rather than a commitment.”

The Climate Council previously described Woodside’s original bid as a “carbon bomb” that would lock in more than 4 billion tonnes of climate pollution – equivalent to a decade of Australia’s annual emissions.

Watt said on Friday the new conditions imposed on the project demonstrated the government was committed to protecting First Nations culture and protecting jobs.

“It’s not one or the other,” he said.
