Sisters to coach against each other in Hampden league for the first time in 2020

But they know the conversation will dry up leading into the Hampden league's opening round as they prepare to coach against one another for the first time.

Barr, 35, and Hinkley, 28, don't expect to stay silent for long - the desire to talk tactics and opponents will be too strong.

Once the Cobden versus North Warrnambool Eagles match is decided they'll revert to old ways.

"The thing I am a bit worried about is we can't debrief with one another," Bombers coach Hinkley said of round one.

"Last year, even in the finals, I was sitting on the sidelines when North was playing Camperdown texting Kim (Wines) who was in Jaime's ear because I think we really bounce off each other and talk to each other about different options."

Barr conceded it would be an unusual feeling.

"We are super competitive. I think that is going to be a challenge that first week," she said.

Hinkley has taken on the Bombers' top role for 2020 after a successful stint with Geelong league club Newtown and Chilwell.

Barr, who is preparing for her second season at the Eagles' helm, hopes the sisters will face off as non-playing coaches in the season-opener at Cobden Recreation Reserve.

Hinkley said it would be a case of wait-and-see after welcoming her first child with husband Paul into the world two weeks ago.

"I am not sure yet if I will be on the court or on the sidelines," she said.

"It will be more interesting if we can glare at each from the sidelines."

Barr is hopeful that scenario comes to fruition, citing her younger sister's on-court dominance as a scary proposition.

"I am definitely hoping she's not playing round one," she joked.

"I am just really excited, we've only ever played together and I've coached Soph so I am really excited she gets this opportunity to be an open netball coach too.

"We are both pretty intense individuals, most people would say that about us but I am really looking forward to seeing how Soph goes with that different aspect of playing netball.

"It's definitely different being on the sidelines and trying to get the best out of people.

"Soph is great leading from on the court so we'll see how she goes with the stress of doing from the side."

Barr and Hinkley, older sisters to teenage brother Taine DeManser, have always enjoyed the intricacies of the sport.

Both credit those foundations for forging their paths to open level coaching.

"We grew up around the netball court, so a lot of thanks goes to mum (Anne DeManser) who was the coach before we were and pretty much taught us most of what we know about coaching," Barr said.

"It was born into us very early on. We want to help people out and we love being involved with people and I think that's probably why we do it."

Hinkley said adaptability was drilled into them as players and was just as crucial, if not more, as a coach.

"We were both really lucky to have great coaches growing up that taught us how to be really good netballers instead of teaching us how to be a really great goal attack or wing attack," she said.

"As players our strength is we are versatile and I think that translates into being able to coach really well because you have that experience and the ability to play in a number of positions so you know what's going on across the court.

"Jaime as a coach has a really broad picture of things and when she coached me one of the best things was she would throw these random combinations together and they would work.

"Jaime always see the potential of different people to play in different positions and that's probably something that I can think (of using) for my coaching."

Competitive spirit aside, the sisters will put round one's result into context.

There is a healthy respect between the pair and their respective clubs.

"We can certainly step back from it, we know it's just a game and I even look at North and think 'I want them to get the best out of themselves'," Hinkley said.

"I want the best for North Warrnambool and every other team in the competition."
