Postman sent 'threatening' notes

The mystery postie has apparently left several notes for the man, insisting he will stop delivering to the home if the owner doesn't clear up his garden.

While the postman says he needs to walk over the grass - which is covered in bushes and greenery - to reach the frontdoor, resident Johnson Ong has claimed the he should just use the clear driveway.

The man, who lives in Australia, wrote on Facebook: ''Post man written warning messages on our letters. demand us to make way for him to ride across the nature strips .. for his convenience way to deliver letters.

''Our garden is looking the same for the past 12 years as u see in the pic. We just received those warning message within past 1 mth ...

some of us did mention about safety to postman. definitely this is very important.

''Riding over nature strips in wet weather is not safe... as it could be slippery.. mud can get into his wheels ... spreading to all neighbours drive way.. Encouraging all riders or drivers to use drive way is the safest for themselves and others. (sic)''

Jonathan did complain to the postal service, but they defended the driver and said he was in his right to make the requests.

Sharing a link to their website, they responded: ''Looking at the photo of your mailbox, the area around it is not clear.

''I apologise if you think the driver is threatening you however they are entitled to ride across nature strips. This is to ensure safe, accurate and fast deliveries.
