The NRL will persist with playing a State of Origin match on neutral turf for the next three years with Adelaide to again host a game in 2023.
The league confirmed on Tuesday morning that Origin would go back to the Adelaide Oval, giving South Australia a chance to host a packed fixture.
Last year's moved end-of-season match had its capacity reduced to half due to COVID-19, with the game still selling out at 50 per cent.
One game has been taken out of Sydney and Brisbane for every series since 2018.
Melbourne will host game one this year, while a match is also expected to go back to Perth in 2022.
There has also been previous interest in New Zealand holding a match.
"We want to build on what we started last year," ARL Commissioner Peter Beattie said.
"The Adelaide Oval match was a great success.
"We had a capacity COVID crowd and the way the city embraced the Origin Series gives us every confidence of filling the venue in 2023.
"State of Origin is the most successful sporting brand in Australia which we now play in the five biggest capital cities in Australia."
NSW won three straight matches on neutral territory in 2015, 2018 and 2019, before they were shocked by Queensland in Adelaide in 2020.
The decision to spread the game's wings comes despite the NRL's preference to push their club expansion with a third team in Brisbane rather than heading interstate.
