Off contract since the end of last summer, AAP can reveal Healy has agreed a contract extension to keep her in the WBBL with Sixers until the end of 2025-26.

Leaving the club was never realistically an option for Healy, with the main decision for Australia's stand-in skipper being how much longer she wanted to commit for.

The 33-year-old has spoken in the past about considering her future, with an ongoing joke between her and husband Mitchell Starc that she has changed her mind multiple times.

Players often continue in franchise cricket after the end of their international career, but Healy's long-term deal is an indication she is not planning to walk away any time soon.

"The only thing we pondered was how long we wanted the deal to be," Healy told AAP of her Sixers contract. "The beauty of the situation is I have had an exciting opportunity to captain the side in the Ashes.

"Whether that is something that will happen moving forward or not doesn't matter. It has reinvigorated the way I think about the game and the way I am enjoying it.

"There is an exciting 12 months ahead with World Cups and trips to Bangladesh. I am still loving playing for Australia, but the WBBL is great to be part of."

Elevated to the captaincy a week before the Ashes tour when Lanning was ruled out, Healy had one of the tougher series of her career with 126 runs at 15.75 across all formats.

She is desperate to rebound, and be better prepared to juggle the captaincy and her own game at short notice.

"It's made me think about what I need as an individual," Healy said. "Throughout my whole career it has just been 'do my job for the team, do what the team needs'.

"I have always enjoyed being vice-captain because that is the way you think; you are in the right position to read the game and help the captain out.

"But being skipper you don't have time to think about anything. You are focusing on the game and tactics, and I forgot to think about what I need to make sure I perform. It has made me think about my game and what I can do to be better."
