The Index, put together by financial services company Taylor Collison, is based on market capitalisation.

The number-one company – oil and gas giant Santos – is no surprise, and was the clear number one on last year’s inaugural list.

However, the Index shows several fast-rising sectors which may challenge the dominant but shrinking energy sector in years to come (read our analysis of the data here).

Companies were considered eligible for the list if they had a South Australian head office, with an Adelaide share registry, or were SA operated, founded and majority-owned by South Australians. Qualifying companies could not be government-run, agencies of government or a registered charity.
