She was probably always going to be good at some athletic pursuit or other given her family background.
But the choice of the round ball has taken her to Wembley and family and friends will be watching back home in Australia.
“He's the reason why I play football,” Rule said of her brother, who is two years her senior and is a semi-pro in the Australian second tier.
“He's the only other one in the family that plays football.
“I always looked up to him and he is also always watching and always telling me what to do and stuff.
“I did a few different sports. I love to surf and I played touch footy (rugby) all that stuff.
“My parents were both athletes, but more my dad was a cyclist and my mum a track athlete.
“And then my brother just started playing football and I just wanted to do everything he did.
“We've shared a bond over football and he's like my best friend, so it's nice.”
Rule’s dad Greg will be at Wembley for the final, which is a midnight kick-off Down Under.
The semi-final away to Liverpool was easier time-wise but not an easy watch as Albion fell 2-0 down.
However, Rule, who plays as an attack-minded right-back, has nothing but good memories and said: “That whole day was just so fun.
“To do that as Brighton, to reach a final, it kind of feels like far away to go to Wembley and go to a final with this team.
“But I think we all knew it was possible and it’s what we are striving for.
“To do it as Brighton and with the group of girls we have at the moment, it's really special.
“And the last-minute winner just is so much excitement.
“There was no better way to do it. It felt like it was meant to be.”
Albion showed belief at St Helens and Rule says that will be key at Wembley.
So the fact they recently beat City 3-2 in the league should help.
“I think it's a good thing in the way that we have that belief.
“I feel like our team is a pretty humble, grounded team.
“We're not individuals that have come from a lot.
“I think this whole season, it has been about believing that we can do it. Like, we are talented enough.
“But in some games we have lost results, just from the fact that maybe we haven't believed that we could.”
In total, Albion lost 19 WSL points in games where they led, including when they went down 2-1 at City early in the season.
But they overturned an early deficit to beat the soon-to-be champions at Broadfield.
That late run boosted belief and Rule’s efforts through the season saw her named as young player of the year.
She said: “It was a bit of a surprise. I didn't know I was eligible for young player at 23 now.
“It was a nice thing to receive. I'm proud of myself and where I've come from last season, not playing much with the injury.
“So just to play a part in this season with this team, it's been a special year.”
