Skye Nicolson sounds to have finally had it with Tiara Brown's fighting words as the pair prepare to clash Down Under this weekend.

"I think it will feel like the most satisfying win of my career," Nicolson tells The Ring. "It almost feels personal."

It's Australia vs. America on Saturday as Queensland's Nicolson (12-0, 1 KOs), the WBC featherweight titleholder, defends her belt against Fort Myers' Brown (18-0, 11 KOs) at the Qudos Bank Arena in Sydney live on DAZN.

The build-up so far has been prickly, as Brown continues to level pot-shots at Nicolson's career. Among her gripes are that Nicolson has been 'spoon-fed' along an 'easy road' to her world title.

The former Washington D.C. police officer has been a professional for nine years and is fighting for world honours against Nicolson for the very first time in her career.

Nicolson, on the other hand, has boxed in seven different countries in just 12 fights, and she became a world champion in her 10th bout against Sarah Mahfoud.

It's therefore easy to see where Brown's frustrations come from. "I was an amateur for 15 years", Nicolson notes, however. "I boxed around the world [in the amateurs], travelled around the world to get all those fights. I moved myself to the other side of the world [to become a pro].

"I think she's kind of convinced herself of this narrative that she's had to do it the hard way," Nicolson adds. "I don't think you can even compare my opponents to her opponents as professionals. I'm sorry, her resume is a joke.

"I think she's going to be rudely shocked when it gets to round two or three and she can't hit me, and I'm smiling at her like I've done to everyone else I've fought. She's going to be getting seriously humbled."

Nicolson hasn't had to use verbals like this for any of her previous fights. Her pro career has been smooth sailing and her corner needn't have bothered bringing an enswell to any of her contests; she's been hit that little.

But the 29-year-old makes it clear she's faced adversity before. To those who have paid attention to Nicolson's career, they'll know she lost in the quarter-finals of the Tokyo 2020 Olympics, losing a 3:2 split to now Boxxer and Sky Sports-promoted Karriss Artingstall.

Following that defeat, Nicolson was left in tears on national TV. She was asked by an Australian reporter after the fight if she could take some pride in being the most successful female fighter in her country's history. "Means nothing to me," she responded.

"I don't regret saying that at all," she says. "I knew what I was capable of achieving at that tournament. And I was set on gold and it was so close. It was like dangling right in front of me.

"I knew that if that decision had gone my way in a fight that could have gone either way, I knew that I was going to go on to win the gold medal. The girl that I would have fought next in the semi-final, I 100% would have beat and she won the gold medal.

"But you know what? I've had so many times like that in my whole boxing journey where I missed national teams. I didn't make the first Commonwealth Games I tried for. I didn't make the first Olympics I tried for. And all of those things shaped me into the fighter and the athlete that I've become."

Nicolson comes from a boxing background, though she wasn't raised with any expectation that she make it her profession.

Her two older brothers Jamie and Gavin, who she never had the chance to meet, were killed in a car crash in 1994, a year before she was born, while on their way to boxing training. Jamie was a promising amateur and competed at the Barcelona Games in 1992, having picked up World and Commonwealth gold in Moscow and Auckland in 1989 and 1990, respectively.

Nicolson's parents Allan and Pat remained connected to boxing, and were relieved when they welcomed a baby girl in Skye to the family as there would be no pressure on her to follow in her brothers' footsteps.

Despite the lack of interest in boxing at first, Nicolson rose the ranks soon after she laced a pair of gloves for the first time. "I was quite a girly girl, and I still am," she says. "I would be roller skating at the back of the hall while the boxing was going on.

"I'm pretty sure there were a few cute boys around the same age as me that were training in our local boxing gym. I honestly think that was the main reason [I started].

"I thought 'I'm holding my own with them'. I'm sparring the boys. If they can do it, I can do it. From there, honestly, I never, ever looked back."

Now settled in London and training at the Ibox Gym with Eddie Lam, Nicolson has found her home from home in her trainer's family.

Nicolson is just under 10,000 miles away from Queensland. Trips home have to be planned well in advance and Aussie Christmases, as a result, have been sacrificed. "I've spent a couple Christmases with the Lam family," she says.

"Honestly, I am like [the Lams'] adopted adult child, which is cool. They've actually got a son and a daughter who are in their 20s as well and I'm very much just part of their family now. It all just works great."

Nicolson has now set her sights on becoming a unified, undisputed and multi-weight world champion. "I want to be in blockbuster fights," she adds. Amanda Serrano has always been a target of Nicolson's. It's yet to be seen how much longer the Puerto Rican decides to keep on fighting past her trilogy fight with Katie Taylor on July 11.

Whatever lies in wait for Nicolson, she's sure to take it all in her stride, just as she has since stepping in between the ropes for the first time at the age of 12.

Assuming she deals with Brown like she says she will, more opportunity avenues will open up for Nicolson. She's still yet to have a single fight in London. An Ellie Scotney fight in the capital is of interest to her. Perhaps even a move up to 130 pounds to challenge her undisputed champion pal Alycia Baumgardner is on the cards.

For now, though, Nicolson's happy to keep it stepping, and everything will fall into place for her from there.

"I'm just walking the path that was already written for me," she says. "I just feel like this was always what was going to happen and what was meant for me. And I can't wait for it to continue."
