Innovative services, healthcare, food and wine are also rising trends among the next 25 businesses (positions 75 to 51).

Combined, these companies contributed more than $1.68 billion to the state’s economy in the past financial year and created jobs for some 4150 South Australians.

The list also reflects existing industries reinventing themselves and setting their sights firmly on the void that will be left by traditional manufacturing.

The power of home improvements has seen Adelaide-headquartered Australian Outdoor Living (72) and Home Australia (51) sit comfortably among top resources performers Cooper Energy (75) and Mayfield Industries (74).

SA’s renowned food and wine sector continues to gain a strong foothold in the list of our state’s top companies, compiled by analysts at Prescott Securities and supported by the University of South Australia and the Adelaide Convention Centre.

Delivering about 200,000 tonnes of wine grapes to the market, Australia’s largest grape supply group, CCW Co-operative (66) in SA’s Riverland, has a workforce of some 600 employees.

Taking premium produce from the pond to the plate, Australian Fishing Enterprises (62) farms and sells tuna to the domestic market and frozen fish to the international market.

Satisfying the South Australian sweet tooth for 100 years,  Haigh’s (71) is Australia’s oldest family chocolate makers and remains a strong top 100 performer by delivering a traditional product in a modern world.

As South Australia’s traditionally dominant industries start to wind down, the state is seeing the rise of stalwart sectors that are rising through the ranks as they capitalising on the state’s growing older population.

Discovery Parks Holdings (56) is luring the lucrative “grey dollar” generated by the convoys of retirees travelling through the state and ACH Group (53) is responding to a call to ensure the state can meet the needs of its growing elderly population.

The remaining South Australian businesses from 50 to 1 of the top 100 will be published by InDaily leading up to the South Australian Business Index lunch on Wednesday, 28 October, with SA Premier Jay Weatherill as one of the guest speakers.
