Join us for the seventh anniversary edition of the SA Business Index – an independent ranking of the state’s top 100 companies – on October 22, 2021.

South Australia has a number of established and burgeoning companies who are stimulating our local economy. Some are known and some are unknown. InDaily has created the South Australia Business Index to pull together data on the top 100 companies in South Australia.

Through our weekly Business Insight issue, InDaily Express morning news and InDaily lunchtime edition, Solstice Media has significantly increased business coverage for South Australia.

This is reinforced by Solstice Media’s event suite including 40 Under 40, Regional Showcase and South Australian Business Index and the work of our Masthead Studio to tailor content to business needs.
