And what of his impact on Jersey sport?

The island has produced top sports people in the past.

Harry Vardon – the first British golfer to win the US Open in 1900 and six-time British Open winner came from the island, while in 1934 Jersey’s Dot Macready won diving gold for England.

Colin Campbell ran at two Olympic Games as well as competing in bobsleigh at the Winter Olympics.

Graeme Le Saux and Matt Banahan played for England at World Cups in football and rugby union respectively, while Serena Guthrie captained England at netball and helped the Red Roses beat Australia for a historic Commonwealth Games gold in 2018.

Jersey had won four Commonwealth Games medals in their own right before Nowacki – the last coming in 1990 when Colin Mallett won fullbore shooting gold before teaming up with his father Cliff to win bronze.

So where does he rank in the pantheon of Jersey sporting greats?

“He’s right up there,” Richard Collinson tells BBC Sport.

The veteran BBC Jersey reporter has covered sport on the island for more than 40 years and also headed up Jersey’s Amateur Swimming Association for a spell in the 1980s.

“He’s going to continue to achieve even greater things than he has done now, which have already been quite outstanding for an 18-year-old,” he added.

“Everybody on the island was hugely excited at Colin and Cliff’s achievements in winning medals in Auckland.

“They were given a huge reception when they got home by everyone, not just people in sport but everyone back home, and I expect Filip will get the same.”

Nowacki will be 22 at the next Commonwealth Games and is also eyeing up the 2028 Olympic Games in Los Angeles.

With the talent and ambition that he has, who is to say he could not become Jersey’s greatest sportsperson of all time?
