Dual protagonist stories are often more powerful than those with just one.
But selling them in a logline is hard.
You now have two clear protagonists, two goals, but no inciting event. What kicks off the story?
There is no need to state explicitly that "their parallel journeys slowly transform how they see each other" because if done well, this is what happens in about every dual protagonist story.
I would leave the word "slowly" out of any summary document because I believe it works against you on a subliminal level.
(Also, 'slowly transform how they see each other' is internal, not filmable.)
How to get to a better logline? Pick one of the two woman as the focus.
Whomever you pick, give her a concrete inciting event and reinforce the external stakes you already set up: the election and the promotion.
Here's the Logline Medic's 'bad version' logline:
"When her daughter dismisses her as just a homemaker, an overlooked Indian mother in Sydney runs for local council against the entrenched incumbent, determined to win a seat before her family writes her off for good."
But you know your story better, so what is the better logline?
