A Brisbane mother is shocked after a stranger left an anonymous and disturbing letter complaining about her autistic son.
Magenta Quinn discovered the note that asks her son to stop making "disturbing" noises in her mailbox on Monday.
The letter, delivered by a neighbour, criticises the boy's "strange moaning and shouting coming from your garden every day and night", which they were concerned "may be illlegal activities".
The neighbour then rang the police, who informed them that her son was autistic.
"Whilst I sympathise with your situation it is a very disturbing noise that comes from your garden continuously... it's not fair on the community to have to bear this disturbance."
"I am giving you the opportunity to live together in this community without it becoming a constant battle.
"If this continues at the regular intervals it has been, I intend to make formal complaints against your address to council to help resolve this issue."
Ms Quinn posted the letter on Facebook to raise awareness of mental health and disability issues.
"I shared it to state "this is not ok" and make a stand about bullying," she wrote.
"Dear neighbour who left me this note, while I appreciate the odd noises of a mentally ill person can be disturbing, I can guarantee that you have no clue when compared to living with it 24/7 for 17 years.
"Having three police turn up at my doorstep at 10:30 at night when I'm new to the area may have made you feel you are avoiding confrontation, but for me it was alarming to say the least.
"Talking with council won't help, he's not a dog, it's a person.
"If you'd like to take him on a holiday so I can get some rest that would be awesome. Otherwise, please feel free to come and chat with me, [as] there's a lot you do not understand."
