Caitlin Parker is guaranteed Australia's first Olympic medal in women's boxing after dominating her quarterfinal against Moroccan world champion Khadija Mardi.

The 75kg chance was the clear victor despite a 4-1 split decision in Paris that has assured Australia two boxing medals at the same Olympics for the first time in 64 years.

There are no bronze medal fights at the Olympics, meaning Parker will leave with a historic medal even if she loses her semifinal against China's Li Qian on Thursday at Roland Garros.

"I have got every emotion going through me right now," she said.

"It's a big relief to have done it and finally secure an Olympic medal. The first female from Australia to have an Olympic medal [in boxing]. History has already been made."

Only six Australians have won Olympic boxing medals, Harry Garside's bronze in Tokyo three years ago snapping a 33-year drought.

None of those six have been gold, but Australia now has two live chances after Charlie Senior (57kg) stormed into the semifinals on Saturday.

Senior fights Uzbekistan's Abdumalik Khalokov for a place in the final on Thursday, just 30 minutes before Parker enters the ring.

Three judges handed all three rounds to Australian boxing captain Parker, who set the tone with a fierce overhand right that connected in the first round.

The 33-year-old mother of three daughters followed that up with a left hook and two left jabs in the second round to leave her taller opponent needing a final-round stoppage to steal the win.

"I can't wait to call mum and dad and scream on the phone honestly. It's mind-blowing," she said.

"Watching Charlie secure our first medal yesterday, I was in absolute bloody tears, and then he came back to the Olympic village and we just cried together.

"It was just an incredible moment. That pumped me up so much and I felt that I had to bring everything, and I did that. I will probably not sleep tonight, just smiling and looking at the roof."

Women's boxing has only been part of the Olympic program since 2012, Parker the first Australian woman to compete at two Games.

Australia qualified a record 12 boxers at this year's Pacific Games in the Solomon Islands.

But Parker, Senior and super heavyweight Teremoana Teremoana Jnr were the only three to progress beyond their first fights.
