(Cosi) Costello

Host of South Aussie with Cosi


Cosi is a proud born and bred South Australian! He grew up on the Yorke Peninsula and studied Agriculture at Roseworthy College. He’s a country lad, who, after winning a radio competition on a local radio station and winning the hearts of the state, has become a household name.

Current Work:

Cosi currently heads up South Aussie with Cosi which is SA’s only true travel show (now in it’s 9th Season!), airing on Sundays at 5.30pm on Channel 9 and weekdays you can hear him on the radio hosting the breakfast show on Hit107 with Bec Morse. He is now a mainstay in media with over 20 years experience, making a name for himself on both 107.1 SAFM and 104.7 Triple M hosting their Breakfast Shows with the likes of John Blackman, Jane Reilly & Amber Petty.

Cosi is proud to dedicate his life to promoting South Australia and those people who call it home. Cosi's main objective is not only to promote SA, but to encourage others to get passionate about living in one of the best places in the world and travel as much as they can with their families.

Cosi is always entertaining and informative when it comes to his interaction with his loyal social media family.

By utilising his TV viewers, radio listeners and over 300,000 Facebook friends, he has a significant voice amongst South Australians and in particular, his online community are extremely engaged and passionate!

He also regularly gives up his time for those doing it tough, by championing community groups who may be less fortunate. He’s organised events such as camping trips for single mums and their kids, annual birthday parties for 100 children who miss out on celebrations through social isolation or illness and movie screenings for children with disabilities and their families. Not limiting himself to helping people locally he also founded his own charity called Cows for Cambodia in 2013, helping hundreds of families break the poverty cycle in one of the world’s most impoverished countries.

In 2018 he was extremely humbled to be nominated and then go on to win the “South Australian Local Hero Award.” This also meant he was a finalist for the "Australian of The Year” where he travelled to Canberra for the awards and was honoured for his achievements in charity and tourism by then Prime Minister Malcolm Turnbull.

Cosi is the perfect fit for any business looking for a high profile ambassador, MC or host.

His online expertise and huge following have been used by many companies to strengthen their branding with incredible results. The passion that Cosi has for life and his positivity is infectious to all those he is around!
