Yet Taurua admits she may be a bumbling mess in Sunday's season decider against NSW Swifts in Brisbane.

Taurua has been the rock behind the Lightning, who could legitimately claim to being Australia's most successful sporting franchise.

They have not only won titles in their first two seasons, the Lightning have also cruised into the 2019 title decider on the back of nine straight wins.

And that includes a 58-48 semi-final triumph over grand final opponents the Swifts.

However, Taurua said she may struggle to keep her emotions in check in Sunday's title decider as she prepares to draw the curtain on her unprecedented Lightning stint after recently announcing she would return to her native New Zealand at season's end for family reasons.

"At the moment I feel quite focused on what needs to happen but when the game starts I could be a bumbling mess," she said on Friday.

"But I am not too worried on how I present myself or the emotion that may come out on Sunday.

"I just want our team to get out there and play and put out that overall performance that we are accustomed to out on court.

"There may be one game left in Lighting colours but as a family I will be around forever."

There is speculation that Taurua will extend her role as New Zealand's World Cup-winning coach into 2020 after leading the Silver Ferns to an historic and unexpected triumph at July's championship.

However, Taurua said her sole focus was inspiring one last hurrah for the Lightning.

"It's massive. It's more of a celebration for our club and the Sunshine Coast, as a community and knowing where we have come from as a newly established club," she said.

"It is amazing that we are in our third straight grand final and with the possibility of winning another premiership, but I don't think there are extra expectations because we have been there done that as such.

"The only expectation we have is on ourselves and make sure we deliver and play that beautiful game we know we are accustomed to."

While Taurua tried to play her accomplishments down, Lightning captain Laura Langman revealed how far the Sunshine Coast had come in 2019 after losing Diamonds stars Caitlin Bassett and Kelsey Browne in the off-season.

"I think in that round one game we were still probably figuring out what our style we would be," she said.

"But everyone has challenged each other under Noels and that has become our recipe for success."
