The Hexham-based teenagers were crowned Hampden league junior netball best and fairest winners in 2018 and are now football teammates, making a mark for Terang Mortlake in the Western Victoria Female Football League under 18 competition.

Jaime, 17, and Tasha, 15, made their football debuts last year and returned to the Bloods' ranks for the coronavirus-impacted 2020 season.

"We get along most of the time. I think sport brings out the best in us, we probably get along best when we're playing sport," Tasha said.

"We do work really well on the netball court at times but like all sisters we have our scraps every now and then."

They only got one football appearance in - Sunday's round one win against Hamilton Kangaroos - this season before the Victorian government's decision to re-introduce stage three restrictions put a premature end to community sport.

Younger sister Tasha said Jaime had eye-catching attributes on the field.

"What I like about Jaime's game is she is really, really fast and she is everywhere where you need her to be and she's always there for the quick handball," she said.

"She gets in there and has a crack even though she is probably the smallest on the ground."

The respect is mutual.

"I like that Tasha doesn't back out of a contest and she'll always contest marks and have a real crack even though she's pretty little too," Jaime said.

The Mortlake College duo plan to pull on the boots again next year, with Jaime saying they "love playing footy".

The midfielders are "still learning" after picking up football late.

"Last year we played a game at school and after that we heard Terang wanted to get a girls' team up and running and we really enjoyed playing at school so we thought it would be good for something to do," Tasha said.

"We turned out to really like it."

Jaime said their new-found sporting passion had come as a surprise and they were playing for enjoyment.

"We hadn't really had much to do with it before then so we hadn't had much experience playing," she said.

The camaraderie appealed to the Killen sisters.

"The atmosphere the girls brought to training and on Saturdays made it really fun and we had a few coaches, like Tania Barbary and 'Jonesy' (Nathan Jones)," Tasha said.

They credited new coach Alison Kenna too, saying she was "really passionate and really encouraging".

Their teammates are also helping their development.

"One of our first-gamers Annabelle Glossop has some footy experience," Tasha said.

"She played with Terang for a few years before she came to girls but she just really gets in there and it's good to have her as part of the team now because she knows a bit about footy and can direct us and tell us where to go.

"The other one is Taylah Casson. She is all-round good at everything and kicked a few goals (on Sunday)."

The siblings are now preparing for at least six more weeks of remote learning inline with state government stage three restrictions to help stop the COVID-19 spread.

The news had different impacts - Tasha prefers to learn in the classroom whereas Jaime is content learning from home.

"I am not too happy about it, I think I work better around people and I find stuff to do at home that gets me distracted," Tasha said.

Jaime said "I am the opposite".

"I love being at home and just being able to do your own thing," she said.
