A group of 11 Victorian regional cities and towns is preparing a bid to host the Commonwealth Games in 2030.

The Greater Shepparton City Council is leading the pioneering bid, which would see the events shared between several Victorian regional centres including Shepparton, Bendigo, Ballarat, Geelong, Mildura, Wodonga and Warrnambool - but not Melbourne.

High-profile figures such as former basketball star Lauren Jackson, former Olympic athlete John Steffensen, former Hawthorn footballer Nick Holland and philanthropist Heloise Pratt are on the 13-member taskforce working group, which is chaired by former Swisse executive Adem Karafili.

Greater Shepparton City Council mayor Dinny Adem, who will formally announce the pitch, called "the people's games" at Victoria Park Lake in Shepparton on Thursday, said if the bid was successful, it would "leave a legacy for millions of people like we have never seen before".
