Australia Post has been deliberately sending the wrong mail to people across the country for years as part of a top-secret nationwide secret Santa program, according to a statement released by the company’s PR team today.

“We’ve been secretly bringing the magic of Christmas to people all throughout the year for as long as we can remember,” the statement reads. “Some people complain because they think we’re mixing up packages by accident, but we also get a lot of happy customers who love the surprises they receive.”

The statement describes how one man who’d been expecting a book from his mum called 12 steps to living drug-free was delighted when he instead received a box of MDMA from the dark web.

“This man is just one of many winners,” the statement says. “We make a list of deliveries and check it twice, then we burn it and just send the parcels wherever we feel like taking them. Another thing we love to do is send Christmas presents out a few months late. Everyone gets presents on December 25 so it’s a lot more special and unexpected to instead get them in June.”
