An Australia Post customer found themselves perplexed after missing the delivery of an important parcel, despite being home throughout the day and even putting up a sign to inform the postal worker of their presence.

Earlier this week, the customer took to Reddit to share their experience, posting a photo of themselves giving a thumbs-up next to a sign affixed to their mailbox.

The sign boldly stated, “Auspost, I am home!”

It continued, “I can help with my package if need be as it is heavy. Please feel free to knock and ask!”

The customer mentioned that this wasn’t the first time they had experienced missed deliveries under similar circumstances.

“Very expensive and large package coming today … ain’t no way in hell I’m driving to the airport to pick it up because of my area’s driver!” they wrote.

“He loves to just put in the ‘we missed you’ note and speed off, and that’s if he even finds the motivation to leave a note at all!”

Despite their precautions, a predictable – if amusing – update soon followed.

“Are you f—— kidding me,” they wrote, holding up a familiar red-and-white collection slip.

Oddly, despite the customer offering to help due to the package’s weight, the “heavy” box was not checked on the card.

The customer’s post sparked a long thread of replies, many of them featuring similar tales of woe.

In follow-up replies, the customer clarified their package had weighed about 9 to 10 kilograms, well within delivery limits.

They also said they had since taken possession of their package.

“Hell, I barely even lodged a minor complaint at the office and haven’t even called up auspost (sic) to back it,” they said.

“I don’t plan on pursuing it because there’s no point, it’d only create more negativity and I already have my package.”

An Australia Post spokesperson said delivery drivers were subject to “strict protocols”, which required them to knock three times and wait 30 seconds.

“Drivers are also required to take a photo of the front door or intercom, and photos can be viewed through the Aus Post app,” the spokesperson said.
