In a tense finish, the 16-year-old swimmer touched the wall in second, to claim her maiden Paralympic Games silver medal - much to the delight of her family back home in Sussex Inlet.

"It was an exciting and terrifying finish all mixed into one," Chelsea Greenwood, who has sore ribs from cheering so much, said.

"Our whole family know how hard Jasmine has worked to get to where she is today and to see her rewarded for that with a silver medal is incredible.

"Thankfully we don't have any neighbours, otherwise they might have thought something was wrong with all the noise we were making."

Before the "hectic night" unfolded as it did, Greenwood admits the whole family was extremely nervous for their Paralympian.

"I personally felt sick all Tuesday and tried not to think about it as much as I could," the mother said.

"We all just tried to keep busy by watching other amazing athletes compete at the Games."

Those nerves were shared by the Shoalhaven High School student, who chatted to her mum pre-race.

"I spoke to her beforehand and she was super nervous," she said.

"She just wanted to get in the water and race, so I reassured her that she'd done all the necessary training to perform to the best of her abilities.

"Adding to the nerves was the fact it was a timed final and not a heat.

"Usually, after the heat, she would have the chance to chat with her coach and tweak a couple of things but not on this occasion.

"On top of that, as Jasmine hadn't had the chance to race internationally recently, there was that unknown of who she was coming up against.

"That and the fact her team bus was late, which prevented her from doing her normal preparation, definitely added to the nerves."

Those all evaporated once the Bay and Basin Amateur Swim Club product hit the water in the Tokyo Aquatic Centre.

"After the race, she was just so relieved - it felt like a huge weight had been lifted off her shoulders," Chelsea Greenwood said.

"Jasmine just wanted to get on the podium, she didn't care about the colour of the medal because she wanted to make her coach and everyone back home proud - which she most definitely has."

While labelling the medal as the "icing on the cake", Greenwood hopes this can be the start of Jasmine's huge Paralympic career.

"I can remember when she first got sick, all she wanted was to get better and was going to do whatever she could to make it happen," Greenwood, whose family's property was damaged by the Black Summer bushfires, said.

"She's had the resiliency from a young age, much like her determination and maturity - she doesn't let anything get in her way from achieving a goal.

"While this is her first Paralympics, the fact she's competed at a Commonwealth Games and World Championships previously acted as her stepping stones to help prepare her for this moment, especially in terms of the pressure she puts on herself to perform.

"I have no doubts this silver medal will be a huge springboard for her career, as she works towards Paris in 2024."

Before that though, the Bernie Regan Memorial Trust grant recipient has two more races in Tokyo.

"She just missed out on a medal in the freestyle but used that as motivation in the butterfly," Greenwood.

"I don't want to put too much pressure on her but she's definitely in the mix for a medal in both the backstroke and individual medley.

"We all know, if she swims to her capabilities on the day, anything is possible."
