For over 25 years, firefighters from Australia's firefighting services have banded together to show off their bodies and raise money for good causes.

The calendars have already raised several million dollars for various charities, including children's hospitals and cancer organizations.

The money raised this year benefits several animal charities, childhood cancer nonprofits, and a group that serves individuals with Down Syndrome. Read more here.
