Soldiers helped veterinarians feed the koalas and built an aviary for them to climb.
When fires raged in Australia, the military helped put them out.
By order of Prime Minister Scott Morrison, 3,000 troops were called in to help evacuate people.
The soldiers had to work hard for several weeks.
They realized how much help they can provide to both people and animals.
The photographs show soldiers holding koalas in their arms.
They helped the veterinarians take care of them, feed the koalas and build a birdhouse so they could climb.
“I invite everyone to visit Australia to see these wonderful animals with their own eyes”, said Captain Garnett Hall.
This is a very good move by these people. We appreciate their willingness to take care of these incredible animals.
