Does Australia exist or is it a just a hoax?
This is the question winding Australians up after Swedish Facebook personality Shelley Floryd announced she refuses to believe the world's sixth-largest country exists.
An army of barely-literate Aussies have been hammering on their keyboards in response to her comments.
"Australia is not real. It's a hoax, made for us to believe that Britain moved over their criminals to someplace. In reality, all these criminals were loaded off the ships into the waters, drowning before they could see land ever again," she says.
"The things these "Australian" says to be doing, all these swear words and actions based on alcoholism, MDMA and bad decisions, are all ways to distract you from the ugly truth that is one of the greatest genocides in history."
Ms Floryd argues the evidence for the existence of Australia is part of a conspiracy to cover-up the death of the criminals.
"Australia does not exist. All things you call 'proof' are actually well fabricated lies and documents made by the leading governments of the world," she says.
"Your Australian friends? They're all actors and computer generated personas, part of the plot to trick the world."
Reception to her message has been negative, with furious Australians battling to convince her that they are, in fact, real.
"IDIOT PUT DOWN THE ICE PIPE OR GO CATCH A SPACESHIP WITH THOSE OTHER NUTTERS > SCIENTOLOGISTS...now ive heard it all... hope a kangaroo kicks some sense into you one day and a koala bites you on the ass," one angry Aussie wrote on Facebook.
"I wish a drop bear would fall out of the sky & rip your bloody face off!!!! If Australia doesn't exist then drop bears do. W***er!!!!!!" another said.
But Ms Floryd has been unmoved.
"Tell the truth. Stand up for what is right. Make sure to spread the world - Australia is not real. It's a codeword for the cold blooded murder of more than a hundred thousand people, and it is not okay," she says.
"We will not, accept this. Stand up for the ones who died. Let it be known, that Australia does not exist.
