The NRL has struck a multimillion-dollar deal with the South Australian government to play a historic match at the Adelaide Oval in 2020.
A press conference is scheduled at the NRL for 10.30 where they are expected to announce more details of the deal.
"We expect 30 per cent of the people who go to the game will come from interstate. That's going to pump $15 million into the economy," South Australia Tourism Minister Leon Bignell said.
"We're hoping to get the middle game, which is obviously a really crucial one. That's on a Sunday. The only problem is we'll have to work with the AFL."
