Dubbo Regional Council has claimed the plaque after donating the most blood and plasma in 2019.
Throughout the year, council staff and loved ones made 306 donations, thereby saving 918 lives.
It was not only the highest donations for the year, but the first time a Dubbo Lifeblood team has made more than 300 donations in the year.
There were more than 100 groups that took part in the Lifeblood challenge in 2019. In total, the participants made 2776 donations of blood and plasma.
In second place was Dubbo Hospital. The team made 165 donations during the 12 months.

Dubbo Donor Centre manager Debbie Garden said it didn't matter how big or small the group was, each donation made a difference.
She said there were teams comprised of only a few people who regularly made the trip to the Dubbo Donor Centre to give blood or plasma.
Council knocked the Dubbo police from the top of the list. In 2018 the Dubbo Police Station staff came in first with 254 donations, while council was second.
