Spot a koala, tap an app and help conserve the species - that's the idea behind a new tool launched as part of the NSW Koala Strategy.
The state government's I Spy a Koala app is free and allows people to record their sightings of the threatened species.
NSW Environment Minister Matt Kean said, "With better knowledge of koala populations across NSW, we can make better conservation decisions."
"Spotting a koala in the wild is an incredible feeling and we all have the opportunity to make sure we see more of them," he said.
He said people should report sick or hurt koalas to a local wildlife rescue group.
The government has also released its first annual report on the strategy, which was launched in May 2018.
It lists 20 of the 24 strategy's actions as complete or in progress, and says the remaining four will make progress during the next 12 months.
