One person’s attempt at a romantic gesture has been slammed online for reckless graffiti, after a frustrated visitor shared a photo of a marriage proposal carved into a rock face at an Australian national park.

The photo shared on Reddit, showed a love heart with the words “Kiri, will you marry me?” carved into a rock fact at the Blue Mountains National Park in Sydney.

While it is unknown whether the proposal was accepted, the act has received backlash online, for defacing part of the world heritage listed site.

“National parks are to preserve. It’s not preserving if everyone is allowed to actively change/alter what’s there on a whim,” one person wrote.

“People are really out here making marriage proposals and gender reveals everybody’s problem. Leave no trace or stay out of the woods,” another commented.

“Dude. World heritage. You’re a w*****,” another added.

Vandalism in a national park can cop hefty fines, with NSW classifying graffiti as “any implement designed or modified to produce a mark that is not readily removable by wiping or by use of water or detergent.”

However, there were a few others who saw a positive side of the situation, with one writing: “Yeah, I’m mad, but in 500 years some nerds are gonna be studying this for a PhD in historical graffiti.”

“They clearly have a rocky relationship as it is,” another quipped.
