Every Australian alive at the time remembers how they felt on September 25 2000.
A nation held its breath as one of Australia's most influential individuals in Cathy Freeman achieved sporting immortality, claiming gold in the women's 400m.
But none were closer in that moment than Freeman's Tasmanian-born basket carrier Rachel Delphin.
Warming up to greatness
The then 17-year-old said the 20-year anniversary of the games had given her a shot of nostalgia in reliving such a monumental occasion.
"I think it's wonderful to say I was the lucky person standing behind her on the track, so it's been an interesting couple of weeks re-living this special moment," Delphin said.
The Devonport-raised athlete had spent her teen years travelling Australia and the world for various sporting occasions.
"I went from the small island of Tasmania to scooping around Australia for different sporting events and then the milestone that was the Sydney Olympics ... I was pretty happy to be a part of all that actually," she said.
Delphin was a member of the Australian team en route to Santiago for the 2000 World Junior Athletics Championships.
"Pre-departing to Santiago for World Juniors, we were asked to volunteer at the Sydney Olympics - there were some very happy athletes who were taking in the opportunity to get up close to their heroes," she said.
"It was actually quite an involved process ... we were still expected to train for Santiago at the same time."
Starting as a hurdle placer, Delphin sought to manoeuvre her way into the basket-carrying side of the volunteering.
"We were up at the crack of dawn on the track ... putting hurdles up ... I saw how close the basket carriers got to the athletes on the track and I wanted to be a little more at the heart of the experience," she said.
"I sweet-talked my way to become what's officially called a basket-carrier."
This led to Delphin being called up to carry for Freeman.
"The historical moment of having Cathy Freeman ... she was a childhood idol of mine ... I distinctly remember my year nine science folder having pictures of her plastered all over it," she said.
"I also competed against Cathy in some of the Tasmanian carnivals in the past, she was in the red and I was in the white so she had to catch me ... I was a little rabbit.
"She didn't quite get there I'm proud to say."

An unforgettable occasion
Standing next to Freeman as she revealed her iconic green jumpsuit, Delphin said maintaining her professionalism at that moment was difficult.
"It was decided that I be that lucky person and I was very privileged to be that person ... it's something that will stay with me a long time I think and It's certainly been pretty awesome looking at it," she said.
"I think it was just the absolute pride - I remember watching her slip on that phenomenal green suit ... I had a little smile.
"Trying very hard to look professional but it was as if Cathy and I were the only people on the track that existed.
"It felt like a bit of a dream actually ... having the opportunity to look back I imagine myself on the track and consider my 17-year-old self and how lucky I was to be standing on that track."
Then after a gunshot, and 49.13 seconds, Delphin was attending to an Olympic gold medallist.
"The magnitude of being on that track at that moment with this huge inspiration of mine," Delphin said.
"She had such a huge responsibility for her country, representing Australia on that day and to feel that energy of a crowd of 119,000 people around her and the exhilaration of that moment was completely overwhelming.
"I think I remember someone having to tell me to get off the track because I was so mesmerised by Cathy."
Reflecting to this day
Delphin now lives in Melbourne, managing a skating business with her partner. But pieces of that moment remain as keepsakes in her life.
"I did manage to retrieve my official coat out of my cupboard ... I popped it on and had a few laughs with friends about how it still fits," she said.
While the moment of glory had passed, Dephin said she continued to employ the inspiration she received everyday.
"I think certainly watching Cathy has reignited a bit of a passion for me personally in terms of things I want to represent for young girls in sport," she said.
"When you put your mind to it and go through that process, particularly with Cathy Freeman: the discipline she put into that sport to get to those places, it was incredible to watch her."
An Olympics to remember
The Sydney Olympics was one of six Tasmanian swimming official Don Blew worked.
He said the event heralded the beginning of a new era of Olympic Games'.
"There was a lot more fuss about it ... It was excellent the way they ran and it will be something you'll always remember really," Blew said.
"Of the six Olympics I've officiated, Sydney was the best."
Fellow Tasmanian and athletic Olympian Susan Andrews said the showing by Australia at the Games was something she'll always remember.
"I think there was just an incredible depth of talent from Australian athletes at the Games - I think a lot of us hung on to our careers because having the Olympics in your own country ... it was a really big call to stay in there," Andrews said.
"There was just amazing talent - to get so many athletes in finals ... I don't think we've done anything like that since.
"The standard of performances from the Australians was incredible and unfortunately we did lose quite a lot of them later on because they retired ... that was the main thing I could remember looking back."
