A redeveloped Adelaide Oval will provide the perfect crucible for the NRL showpiece, after the South Australian government reached an agreement to host the event.

Adelaide follows Perth, which recently secured the rights to a State of Origin match in 2019. Neither state has confirmed which match of the three game series will take place in their cities. 

South Australia expect more than 30% of attendees to visit from outside of the state, delivering an expected $15 million into the local economy. Although there were some suggestions that the game should have been held in a more traditional, regional NRL hotbed.

NRL CEO Todd Greenberg was unsurprisingly excited about the prospect of growth and expansion.

"Adelaide is a new market in terms of hosting this match but we know that Origin is a popular event in the city, as it is across the country," he said.

"That will only be enhanced when Origin is played at such a historic venue like Adelaide Oval."
