Oil and gas producers have experienced significant revenue volatility. Changes in oil and gas prices, exchange rate movements, annual production volumes, and domestic and export demand for oil and gas all influence the industry’s performance. Output has expanded over the past decade, while world oil and natural gas prices have displayed significant volatility. Australia's natural gas production, which comprises most of the industry, has soared over the past decade as new gas fields have been developed to feed Australia's liquefied natural gas (LNG) facilities. Global trade in LNG has expanded, with growing demand for LNG in Asian markets and weakness in the Australian dollar benefiting Australian producers. The industry has invested in several major gas export projects over the past decade, which have increased Australia's LNG production capacity to 88.0 million tonnes per annum. Industry revenue is expected to have inched upwards at an annualised 0.5% over the five years through 2024-25, to $100.3 billion. Rising oil and gas prices in the fallout of the Russia-Ukraine conflict sent revenue skyrocketing and expanded the industry’s profitability over the two years through 2022-23. However, industry revenue is expected to fall for the second consecutive year in 2024-25, dropping 5.0%, as prices for oil and liquified petroleum gas continue to recede and volumes drop. Recent high prices have caused some projects to be restarted and new projects to be green-lit. However, the major oil and gas producers have taken the opportunity to futureproof their portfolios, divesting low-quality assets in the face of rising public concern over environmental issues. Merger and acquisition activity in global oil and gas markets is set to intensify as producers look to consolidate their position and strengthen their balance sheets. Government intervention in domestic gas markets has also created regulatory uncertainty, which is likely to constrain investment in Australia's oil and gas sector going forwards. Ongoing price declines and falling oil and gas production will drive a forecast annualised 5.9% drop in industry revenue over the five years through 2029-30, to $73.8 billion.
