New basins will be opened up. New pipelines will be laid. New gas-burning power stations will be built.
What will all this mean for climate change and Australia's commitment to cut emissions?
Much has been said about the new gas hubs, power stations and pipelines.
But emissions from those will be chump change compared to the emissions that will likely result from the opening up of even a single large gas basin.
The Government is talking about developing five new basins that it will help fund.
Such a move is a proverbial red rag to conservationists who are fighting to stop global warming at 2 degrees Celsius and whose mantra for years has been, "Keep it in the ground".
Take the most advanced of these basins, already backed by the Government: the Beetaloo sub basin in the Northern Territory.

Adding that to our emissions tally will make meeting Paris targets much harder — and it means we'll have to find cuts in other areas, which the Government doesn't yet have a plan for.
Estimates have suggested there's enough gas in the Beetaloo basin to satisfy Australia's demand for 200 years.
But if we need our emissions to hit net zero in about 30 years, it's unlikely the demand for gas will last anywhere near that long.
Some big fossil-fuel companies have acknowledged that. BP's latest modelling suggests there will only be a small increase in the demand for gas if the world does nothing to combat climate change.
Dozens of potential gas projects
The Government has listed dozens of new gas projects that have been proposed by industry around Australia.
A report by The Australia Institute, commissioned by the Australian Conservation Foundation, added up how much greenhouse gas would be released into the atmosphere if these projects all progressed to their full potential.
The figure is not realistic since they wouldn't all progress, and of those that do, not all their gas would be extracted.
But it's indicative of how carbon intensive a gas-led economy could be.

Combined with the gas from the Beetaloo basin, the progressive think tank estimated the potential projects would result in an average of 332 million tonnes of CO2 being emitted each year.
That's about two thirds of our current total emissions.
It's a carbon bubble that would be hard to make up for in other sectors.
The figure combines estimates of the CO2 emitted when the gas is burned, as well as fugitive emissions of methane — essentially, gas leaks.
But there are also concerns even after gas wells are closed, they might continue to leak methane into the atmosphere, making future action to stop emissions difficult.
UN report singles out Australia
The dilemma posed by opening up new fossil-fuel reserves has been analysed by the United Nations in what's called the Production Gap Report.
It notes specifically governments' support of the production of fossil fuels, including gas, "undercuts efforts, sometimes by these same governments, to reduce emissions".
Overall, the report found around the world, countries are planning to produce 50 per cent more fossil fuels in 2030 than would be needed to limit warming to 2C and 120 per cent more than is consistent with 1.5 degrees.

Australia's proposed fossil-fuel projects represent "one of the world's largest fossil-fuel expansions", the report said.
"The rise of hydraulic fracking has also opened the door to discussions on tapping into the country's vast resources of unconventional gas."
The report notes that while global coal production needs to drop by about two thirds by 2030, gas production needs to drop significantly too — by about 20 per cent by 2030 — in order to keep warming at 1.5C.
Under the rules of the Paris agreement, we don't need to worry about the emissions from much of our coal and gas because it's exported, and therefore counted in other country's emissions targets.
According to the UN's report though, the whole world is ramping up production of fossil fuels, so the question of who will take responsibility for that carbon remains.
Gas vs coal
Federal Energy and Emissions Reduction Minister Angus Taylor has also argued gas produces lower emissions than coal, and using gas instead of coal will help lower emissions.
"The success of our LNG exports means that we can help lower global emissions below what they would otherwise have been by up to 27 per cent of Australia's annual emissions," Mr Taylor said.
The UN's Production Gap Report dealt with this argument head on, noting increasing the supply of gas would drive its uptake.

The Government could simply force Australia's big gas exporters to sell more of what they already produce at home, argues Ian Verrender. Read more

"Barring dramatic, unexpected advances in carbon capture and storage (CCS) technology, these declines mean that most of the world's proven fossil-fuel reserves must be left unburned," the report said.
Making the unexpected happen is something the Government is betting on.
As part of its Technology Investment Roadmap, it's investing in CCS, which has the potential to bury some of the emissions from these projects underground.
The world's largest attempt at this is taking place at Chevron's Gorgon gas project in Western Australia.
The project planned to offset only 40 per cent of its emissions using CCS — and it's been plagued with problems and delays, and didn't capture any carbon for the first three years of its operation.
And, since the world including Australia, has committed to stopping global warming, it's hard to see exactly where our domestic gas push is leading.
