South Australian Business Index 2021

InDaily’s annual ranking of the state’s top 100 companies by market capitalisation and revenue covers the 2020-21 financial year and includes a mix of newcomers, improvers and companies sliding rapidly down the rankings.

The list, compiled for InDaily by Adelaide financial services firm Taylor Collison, is the state’s most definitive guide to our top companies (scroll to the bottom of the page for eligibility criteria).

The countdown begins today, with the companies ranked 100 to 81, and will continue all week – with the top 20 and full list revealed on Friday.

Family-owned businesses are strongly represented in this first section of the list, which is headlined by Cochrane’s Transport at No. 81.

Owned by Peter Cochrane and based at its new $20 million Gillman depot, the company has more than 45 years of experience delivering across Adelaide and Regional SA plus Mildura and Broken Hill.

Another family business, air conditioning specialists Mannix Electrical have entered the Top 100 this year at 98 along with listed graphene developer Sparc Technologies at No. 100.

The owner of the Kanmantoo copper-gold mine in the Adelaide Hills, Hillgrove Resources, rejoins the list at 96 after a 12-month absence while commercial builders Kennett and pub group Matthews Hotels also join the list in 2021.

It was a tough year for some of the state’s engineering firms with RJE Global falling 36 spots to 88 and GPA Engineering dropping 22 spots to 97.

Bushfire-ravaged Kangaroo Island Plantation Timber tumbled 13 places to 82 after its $40 million Smith Bay port application was rejected by the State Government.

Angove Family Winemakers were also down 13 places to 86 and specialist supplier of lifting and rigging solutions A Noble & Son were down 14 positions to 93.

Family-owned fuel distributor L H Perry & Sons fell into this section of the list this year, down 13 places from No.72 in 2020.

Some notable omissions from the 2021 list included builder Rivergum Homes, which was ranked 101 after being No. 89 last year and No. 61 in 2019.

VIP Home Services (102), software company Prophecy International Holdings (103), IJF Australia (104) and LBT Innovations (106) all fell out of the top 100 after featuring last year.
