And there's still a few storylines to play out as she prepares to step onto the court at Brisbane's Roland Cowland Stadium on Saturday night for Bendigo Lady Braves in their SEABL east conference elimination final.

The polite and pleasant 16-year-old is in her first season with the Braves, playing alongside the likes of SEABL stalwarts Kelly and Andrea Wilson, Jane Chalmers, WNBL signing Keely Froling and American import Chante Black, a former WNBA top 10 draft pick.

It's no wonder Rennie says she sometimes has to pinch herself to believe it's all true.

Not that the Bendigo South East College year 10 student has been overawed.

Rennie has played at a level that belied her young age from day one.

The youngster calmly slotted four three-point attempts in her SEABL debut against Ballarat Rush in round one as the Lady Braves won a thriller by three points.

Along the way there's been some other handy performances, including a six-point game in a win  against Geelong Supercats on July 9, and eight points against the Basketball Australia Centre of Excellence in May.

In total she's played nine games, averaging 4.8 points per game, underpinned by 13 three-pointers from 34 attempts at the tidy average of 38.2 per cent.

Rennie was surprised to get the call to play so early in the season from coach Jonathan Goodman, but admits it had worked in her favour.

"There was no time to be nervous really," she said.

"At first I didn't expect to go on because I didn't play at all in the first half.

"But then Jon subbed me in, played some defence and then got the first shot that fell, which gave me a lot more confidence."

Rennie, who was aged 15 when the SEABL season tipped-off in April (she turned 16 in May), said she considered herself fortunate to have role modes such as Kelly Wilson to look up to at the Lady Braves.

The WNBL 300-gamer, who has signed with reigning premiers Townsville Fire this season, also happens to be Rennie's mentor in the Athlete Development Program (ADP) at BSE College.

The Lady Braves fly out to Brisbane on Saturday morning, secure in the knowledge they defeated the Spartans a fortnight ago by 13 points, albeit played at Bendigo Stadium.

While they will again be without their captain due to injury, Rennie said the team would enter the cut-throat clash with a fair degree of confidence, after four straight wins.

"Everyone after training (Thursday) night and Tuesday night was fairly confident," she said.

"We've been training really hard and we're keen to do well.

"It will be challenge, but everyone knows they have to step up without Kelly and play roles they might not play all the time.

"We've been training without her, so we know what it's like to have her missing."

Rennie has only recently returned from representing Victoria at the School Sport Australia under 18 championships, together with Braves teammate Madeline Sexton.

Victoria claimed the silver medal, behind arch-rivals New South Wales.

Rennie was grateful for the support of her Lady Braves coach, ADP staff including her teammate Wilson and Bendigo Braves captain Chris Hogan, and of course her family.

“Definitely mum and dad, and all my family – my grandparents and aunty – they drive me everywhere, every weekend,” she said.

“They put in a lot of time, so it’s good to make them proud.”
