Several Greek Australians have been recognised in The Advertiser’s 2026 Power 1000, a comprehensive ranking of South Australia’s most influential figures across politics, business, sport and entertainment.
Dimi Kyriazis and Steve Kosmidis

At No. 77, Dimi Kyriazis and Steve Kosmidis were acknowledged for their takeover of iconic ice cream brand Golden North.
Kosmidis, who sold his X Convenience petrol station chain to BP in 2024, joined forces with Kyriazis to acquire the company.
The pair plan to relocate production from Laura to Murray Bridge, expand output of ice cream tubs and products such as Giant Twins, and explore opportunities in cheeses and other dairy products.
Chris Kourakis

Former Chief Justice Chris Kourakis ranked 73. One of the nation’s most experienced jurists, he retired in February 2026 after more than 40 years in law.
The son of Greek migrants from Ikaria to the Eyre Peninsula, he was admitted in 1982, made silk in 1997, served five years as Solicitor-General and became the state’s ninth Chief Justice, overseeing judicial administration and acting as the court’s spokesman.
His long-held ambition for a major court upgrade, however, remained unfulfilled.
Kayla Itsines

Fitness entrepreneur Kayla Itsines placed 72. The Sweat co-founder and head trainer commands nearly 16 million Instagram followers, has endorsements including Powerade, and has grown the app into more than 50 programs featuring 13,000 workouts.
Theo and Steve Maras

Property leaders Theo Maras and Steve Maras ranked 64. Through the Maras Group, they own significant property in Adelaide’s east end.
Theo chairs the Central Market Authority, while Steve chairs the Adelaide Economic Development Agency and serves on several boards.
Tom Koutsantonis

In politics, Tom Koutsantonis rose to No. 6 after returning as Treasurer in September following Stephen Mullighan’s retirement.
Described by Premier Peter Malinauskas in 2022 as “a loyal Labor lion,” he remains highly regarded in business circles, particularly for his Energy and Mining expertise, despite controversy over the shelved $593 million hydrogen power plant at Whyalla.
