England's Rugby Football League and the Australian rugby union's governing body had previously said they wouldn't offer Barba a contract if he was banned by the NRL.
NRL chief executive Todd Greenberg says he's been de-registered after the integrity commission saw the video.
The Sunday Telegraph is reporting police and the NRL Integrity Unit will investigate three separate incidents, including a heated verbal exchange in the swimming pool area of the hotel in front of several Cowboys players and their partners; an alleged physical clash inside the casino which was caught on CCTV; and another alleged physical incident in the carpark before the pair left together in a taxi. "It's time for Ben Barba to find a new vocation", Greenberg said.
"In the jurisdiction that I uphold there's no place for him".
The English RFL has shot down any chance of the Queenslander returning to the United Kingdom - where Barba resurrected his career with St Helens which resulted in North Queensland giving him another shot at playing NRL.
Having debuted in 2008, Barba won the 2012 Dally M and led Canterbury to the grand final that year before his career first spiralled out of control.
"I can't see a time any time in the future when he'll be welcomed back".

A local official said evidence suggested the collapse, at a mine owned by Brazilian company Vale SA, was caused by liquefaction. The sledge caused by the dam collapse tracked straight for Vale's cafeteria, where numerous workers were eating lunch.
"We'll treat every case on its merits, but when there's violence and where there's violence against women it will sit on top of the scale, " he said.
Other sporting bodies including the English Super League have indicated they will support the NRL's ban on Barba and other players.
He was stood down by the Bulldogs to seek help for alcohol and gambling issues, amid rumours of a domestic violence incident.
He was on his final warning at the Cowboys after being booted from the NRL in 2016 for recording a second illicit drugs strike following his former club Cronulla's premiership.
Speaking of his decision on Tuesday, Greenberg said: "This is an enormous outcome because this is a guy that now loses his livelihood and career in the game".
It's a very clear message for a lot of players in our sport that it's a great privilege to play rugby league, to put a jersey on, to earn a significant income which they deserve as footballers.
