Kath Koschel, founder of not-for-profit organisation Kindness Factory, has been named NSW's 2025 Australian of the Year.
She received the award at a ceremony in Sydney on Thursday night.
Nominees in other categories included popular ABC presenter Karl Kruszelnicki, who won Senior Australian of the Year for NSW for his work bringing science to the masses.
Ms Koschel, a former cricket and ironman competitor, broke her back for the second time in five years when she was hit by a four-wheel drive.
After defying predictions she would not walk again, Ms Koschel turned her attention to spreading the love to others and started Kindness Factory, a curriculum taught at more than 3500 schools Australia-wide about the power of being nice.
With the initial goal of encouraging one million acts of kindness, her work has now spurred on a whopping 7.5 million acts in what has become a global movement.

His weekly show Science with Dr Karl is regularly one of Australia's most downloaded podcasts.

The United Nations awarded him the UNESCO Kalinga Prize in 2019 for popularisation of science.
