Over the years, Imondi collaborated under the pseudonym Videoteppista with various guerilla film groups and grassroots medias, including SKA TV in Melbourne, Indymedia Italy, and Berlin-based videoactivist collective Ak-Kraak.
His first documentary, Waking up the Nation (2002, 2005), a guerilla film, told the story of a group of Australian human rights activists, who travel on an old bus, the Freedom Bus, to visit asylum seekers imprisoned in immigration detention centres across the country. Shot and released in Australia in 2002, the film was primarely used by Australian human rights groups for their campaigns. Upon his return to Europe, Imondi re-edited the documentary for international audiences, where the film had limited screenings in German movie theatres, as well as being screened at some international film festivals.
In 2003 he worked with British director Christina Hotz on the Dutch -South African co-production Orange Farm Water Crisis, which deals with water privatisation in the South African township Orange Farm. The short documentary was screened at various film festivals around the world.
After moving to Berlin he worked as editor on Unsere Mutter (Our Mother), an experimental film by Iranian filmmakers Kia Kiarostami and Daryush Shokof, shot by Kiarostami and fellow Iranian director Bahman Ghobadi.
In 2006 he started research for a new documentary, which later would become the film Neukölln Unlimited, co-directed with the German director Dietmar Ratsch. For this movie he won a Crystal Bear at the 60th Berlin International Film Festival in 2010.
