Dell'Oca who had also worked for the SABC before joining SuperSport in 2018 has relocated with his wife to Ireland.
The award-winning journalist and sports commentator has anchored many top international sporting events including over various sporting codes.
"He dropped a message on WhatsApp to confirm that he is leaving.
"He said his wife had received a job offer in Ireland that they couldn't refuse and will be moving to Dublin soon," a SuperSport colleague confirmed.
"Its a big loss as he remains one of the most talented sports commentators that we have in the country.
"But life goes on, and we wish him all the best for his future."
SuperSport are expected from 1 May to welcome back Thomas Mlambo to the pay channel from the SABC.
