There's a little ditty being hummed and sung around the streets of Forster Tuncurry, and it comes all the way from South Korea.
Yes that's right South Korea.
Penned by former Taekwondo Australia chairman, John Walker, the song is a tribute to the Ninja Nannies, a group of fitness enthusiasts who meet three times a week in Forster.
According to Forster taekwondo master, Fay Shacklock who established the Ninja Nannies 13 years ago, Mr Walker was a great fan of the group and had followed them on social media from his South Korean home.
Mr Walker is more than a Ninja Nannies follower, he also nominated Fay Australian Taekwondo's inaugural ambassador in 2017.
"John said the Ninja Nannies were very inspirational and asked me if he could write a song about them," Fay said.
"I was so humbled and I thought it was lovely."
According to Fay, John Walker has a successful rock band in the country renowned for its unique K-pop culture.
Since the Ninja Nannies was formed it has gained a steady following of women who get together for a hour-long morning sessions of exercise classes encompassing modified martial arts.
The classes are held outside the Forster Tourist Information Centre on Tuesday, Thursday and Friday.
The classes help the women gain more strength and flexibility, which in turn helps prevent falls, and at the same time provides a sense of confidence and improves mental health and self esteem, Fay said.
"Some women say they have gained up to 30 per cent more strength," she said.
"They have a bounce in their step and families are happy because they can see a smile on their mother's and wife's faces,"
Pre-covid up to 150 women, aged from their 50s to 70s, would participate in the classes.
However that number has been whittled down to about 20 to comply with government restrictions.
Fay believed her type of taekwondo program was one of the biggest in the country and possibly South Korea.
Fay said there were plans to present the song to the world taekwondo president, an organisation which has more than 53 million enthusiasts world-wide.
