Mega projects such as the proposed development of the biggest new gas field in Australia have been promised a quicker decision under a coalition government.
Opposition leader Peter Dutton said on Monday a government he led would have "sensible approval processes that don't go on for years and years".
"The problem for Anthony Albanese and Tanya Plibersek is that they're trying to please people in inner-city Sydney and Melbourne who are potential Greens voters," he told reporters in Kalgoorlie, Western Australia.
"And frankly, that's costing jobs here in WA and that's not something that we will abide," he said.
But Woodside Energy's $30 billion-plus Browse project off the WA coast near Scott Reef needs state and federal government environmental approvals to proceed.
Amid reports the project in one of the world's richest marine zones has failed to get state environmental approval, Woodside said it was still working with regulators.
Australia's largest untapped offshore gas resource, Browse is located about 425 km north of Broome in the offshore Browse Basin and is a major component in Woodside's Burrup Hub gas expansion.
"We continue to work with relevant regulators to progress environmental approvals for Browse," a Woodside spokeswoman said.
"Browse is an important resource that could help address the shortfall of domestic gas in Western Australia forecast from the early 2030s and support energy security in Asia."
The project has been found to have "unacceptable" potential impacts on endangered Pygmy Blue Whales and Green Turtles, with the risk of pollution and oil spills also behind the yet-to-be-announced decision, WAtoday reported.
WA Greens MLC Brad Pettitt said WA gas, which was largely exported to Asian markets, was displacing the uptake of cleaner and cheaper renewable energy in the region.
"Woodside wants to keep making a profit from new fossil fuel projects that our climate cannot afford," he said.
"They must listen to the independent experts at the EPA (Environmental Protection Authority), and the WA community, and accept this climate bomb is not compatible with a safe climate or a safe future."
Browse was also aligned with the federal strategy that acknowledged the role of gas in Australia's energy transition to 2050 and beyond, Woodside said.
But environmentalists say Browse gas used in Australia or overseas would dump carbon emissions into the atmosphere, heating the climate and fuelling destruction in Australia.
Jess Beckerling, executive director of the Conservation Council of WA, said it was a major blow for Woodside's plan to develop the biggest new gas field in Australia.
"It is now incumbent on the WA and federal governments to respect this independent scientific advice and expert opinion, and refuse Woodside's application to develop Browse," she said.
Paul Gamblin, WA director of the Australian Marine Conservation Society, said "Scott Reef is not owned by the oil and gas industry, it belongs to us all".
