Naked charity calendar season is upon once again, and we’re getting warmed up by this Aussie dreamboats. We hope they’ve got their hoses, ’cause our pussy’s on fire.

The calendar has been running since 1993 and is available in a variety of different versions: firefighters with dogs, firefighters with cats, firefighters with animals in general, and just firefighters on their own. They’re really after pet owner’s coin.

Last year’s raised money for Mates4Mates, Australia Zoo Wildlife Warriors, Precious Paws Animal Rescue, among others.

“We felt it was important to use the calendar’s social media presence to shine a light on the incredible work they all do,” said David Rogers, Director of the calendar.
