Historical highlights

Founded in 1954, Santos has grown to become one of Australia’s leading domestic gas producers.

In 2014, we celebrated our 60th anniversary. Our timeline of events and achievements highlights how far we’ve come.



Santos Ltd is incorporated in Adelaide, South Australia, on 18 March. The first Directors are Mr John Bonython AO, Major General George William Symes, Mr R F Bristowe, Sir Henry Simpson Newland and Sir Douglas Mawson.


The gas discovery at Gidgealpa 2 flows at 3.2 million cubic feet per day: the first encouraging discovery of natural gas in the Cooper Basin.


The Moomba gas field is discovered which, together with the Gidgealpa field, provide reserves to satisfy the then South Australian market. This justifies the construction of a pipeline to Adelaide and the signing of a sales contract with the South Australian Gas Company, the state’s gas marketing utility.


Construction of gas processing facilities at Moomba begins.


The 790 kilometre pipeline to transport natural gas to Adelaide is completed and, on 10 November, gas is sold to the first customer: the South Australian Gas Company. A sales contract with the Electricity Trust of South Australia is also signed.


Popular opinion believed the Cooper Basin was only a gas resource. This was dispelled in 1970 when gas and light crude oil were discovered at Tirrawarra 1, with oil flows of 650 barrels per day and gas flows of 7.8 million cubic feet per day.


A Letter of Agreement is signed to provide gas to the New South Wales gas utility, the Australian Gas Light Company.


Workers commence construction of a pipeline to transport gas to New South Wales.


Moomba experiences the worst flood in its recorded history, denying road access to the area for six months. The record rainfall is approximately 34 inches, compared to an average annual rainfall of three inches.

South Australian Parliament enacts the Cooper Basin (Ratification) Act


The Cooper Basin (Ratification) Act facilitating the rationalised development of Cooper Basin gas reserves is covered by the South Australian Cooper Basin Unit Agreement. This innovative agreement enables Santos to supply gas concurrently to South Australia and New South Wales.


Supply of gas to New South Wales commences. Gas is discovered in the Eromanga Basin which overlies the Cooper Basin. Oil discoveries in the Eromanga Basin follow.


Santos shareholders receive their first dividend of two cents per share, 24 years after incorporation. The Strzelecki 3 well flows at 2,400 barrels of oil per day: the highest onshore flow rate recorded at that stage.


South Australian Parliament approves the Indenture Bill for the Cooper Basin liquids project, signalling the go-ahead for the $1.4 billion project to process and market liquid hydrocarbons from the Cooper/Eromanga Basins. Jackson 1 in the Queensland section of the Cooper/Eromanga Basins flows at 3,878 barrels of oil per day.


Santos signs the US$600 million loan agreement for the Cooper Basin liquids project: one of the largest loans raised by an Australian company at the time. The port facility is later named Port Bonython, in honour of Santos’ founding Chairman, Mr John Bonython AO.

A significant liquids-rich gas discovery is made at Elevala 1 in Papua New Guinea. The Talisman oil field commences production, marking Santos’ first offshore production and the first from the Carnarvon Basin, off the Western Australian coast.


An historic agreement to sell natural gas across state borders is struck allowing the sale of gas from south-west Queensland to South Australian customers.


The first phase of the south-west Queensland gas project is completed with the construction of the 180 kilometre raw gas pipeline linking Ballera to the Moomba plant.


The upstream assets of the Australian Gas Light Company are acquired, extending Santos’ onshore interests to include producing assets in the Surat Basin and Denison Trough, eastern Queensland, and the Timor Gap. Stage 1 of the gas processing plant at Ballera is completed for gas sales to South Australia. Santos farms into the WA-209-P block in the Carnarvon Basin by funding 70% of the cost of the Stag 1 oil discovery.
