The state government is set to overturn a ban to cage fighting in Western Australia, bringing it into line with other states across the country.
Hosting mixed martial art fights inside an octagon arena was banned by the Liberal government back in 2013 - with fights only being allowed inside a boxing ring.
The move could open to the door for the Perth Arena to host an event as early as 2018.
Lifting the ban was an election commitment from the McGowan government as Sport Minister Mick Murray announcing on Wednesday the changes would come into effect within days.
"MMA isn't everyone's cup of tea, but we want it to take place in the safest environment possible," Mr Murray said.
"The last thing we want to do is drive MMA underground.
"MMA is already legal and taking place across Perth at a grassroots level, but athletes and promoters have been left frustrated that they can't use the standard safety equipment for their sport."
The UFC have praised the move.
"This is a major milestone for mixed martial arts in Western Australia which will allow the sport to flourish," the organisation said in a statement.
"UFC looks forward to hosting its first live event in Western Australia for its patient and passionate local fans.
But the Australian Medical Association has blasted a move to legalise the sport, saying long-term injuries in the sport were more brutal than the sport itself.
AMA WA president Andrew Miller said ringside doctors should not encourage people to be part of a sport where the goal was to "beat your opponent unconscious", rejecting the premier's claim that the move would make the sport safer.
"The AMA in WA is very disappointed to see the McGowan government is driving the wrong way down the freeway of health," he said.
Dr Miller said frequent blows to the head could cause brain bleeding leading to death, personality problems, depression and dementia.
"I would enjoy the sport myself if I didn't know the scientific damage that was being done to young people's brains as a result of this ridiculous past time," he said.
Mr Murray said fighters should undergo strict health checks before and after entering the ring.
Cage fighting was banned under former premier Colin Barnett, who described the sport as gladiatorial and violent.
