[1] The Heat finished the regular season with seven-straight wins but suffered an "epic meltdown"[2] in a twelve-run semi-final loss against the Sydney Thunder, ending their hunt for a three-peat.

[86] On 4 September, CA announced changes to the schedule which would see the tournament begin a week later, on October 25, and be played entirely in Sydney as a result of ongoing uncertainty surrounding state border restrictions.

Requiring 24 runs from the remaining 26 balls, Webb (46 not out off 28) saw the Renegades across the line with six wickets in hand inside the last over, mirroring her finishing heroics of a similarly tight encounter between the two teams in WBBL|05.

Hayley Silver-Holmes, who had missed several previous games due to injury, was named in the team line-up despite not having yet been granted approval by the W/BBL Technical Committee to be added back into the official squad.

[102][103][104] Tammy Beaumont launched the Sydney Thunder off to a fast start with 27 runs from 20 deliveries, though she was brought undone by a Nicola Hancock slower ball during the last over of the powerplay.

The Thunder struggled throughout the middle portion of the innings, especially troubled by Brisbane Heat bowlers Nadine de Klerk and Amelia Kerr who collectively managed economical figures of 3/30 from seven overs.

Thunder captain Rachael Haynes ensured a respectable total for her team, finishing on 48 not out, as Sydney scored 15 from the final over and set Brisbane a target of 144 for victory.

Thunder spinner Samantha Bates struck early in the run chase, bowling Grace Harris for six, before being hit for three consecutive boundaries in the fourth over by Georgia Redmayne.

On the last delivery of the 17th over, with the Brisbane Heat needing just 16 runs to win, Laura Kimmince attempted a high-risk reverse slog against Samantha Bates, only to miss the ball which deflected off her thigh before crashing into the stumps—the bails, this time, were sent airborne.

Sammy-Jo Johnson completed the Thunder's remarkable resurrection on the third ball of the 19th over, removing Delissa Kimmince for a golden duck via caught-and-bowled, sealing a twelve-run victory and cementing Sydney's spot in Saturday's final.

"[2] From the first over of the match, the Melbourne Stars top-order was dominated by a "fiery"[112] spell from Sydney Thunder pace bowler Shabnim Ismail, who regularly beat the bat of Elyse Villani and created two catching opportunities against Meg Lanning before dismissing both players for scores of one and 13 respectively.

After being dropped on zero by Tammy Beaumont at point, as well as surviving a half-chance which Sammy-Jo Johnson put down at third man, Lanning's seven-ball battle with Ismail came to an end when she edged a seaming delivery through to wicket-keeper Tahlia Wilson at the start of the seventh over.

Thunder captain Rachael Haynes was praised for "sensing the moment"[113] by taking the tactical risk of persisting with Ismail, leading to Lanning's wicket which several media outlets described as the defining moment of the match: writing for The Sydney Morning Herald, Tom Decent said "this was the Thunder's night about a quarter of an hour into the contest,"[3] while the Australian Associated Press suggested the "Stars' shot at a maiden title was realistically gone inside 37 balls.

Johnson, having opened the bowling with Ismail and proving similarly difficult to score against, finished with match-best figures of 2/11 off four overs which included claiming the wicket of Mignon du Preez via LBW during the powerplay.

The Sydney Thunder consequently claimed their second WBBL championship, having also won the inaugural title—only Haynes and Samantha Bates were members of both successful squads, the latter missing the WBBL|01 final due to a broken wrist injury sustained earlier in the tournament.

Source: [123] The selection panel for the Team of the Tournament was made up of former players Lisa Sthalekar (Seven Network) and Mel Jones (Fox Cricket), cricket.com.au journalist Laura Jolly and national selector Shawn Flegler.

The team is intended to mimic regular WBBL conditions such as a maximum of three overseas players, a realistic mix of batters and bowlers, as well as a captain, wicket-keeper, twelfth man and coach.

[123][125] The nominees for the WBBL|06 Young Gun were: Adelaide Strikers fast bowler Darcie Brown took out the overall award, having claimed ten wickets in her debut season at an economy rate of 5.52 runs per over.

On 15 October, CA announced Fox Cricket would broadcast an additional twelve matches—the mid-week fixtures at Blacktown International Sportspark—bringing the total number of televised WBBL|06 games to 36.
