Renter Sharon Knoll suspected something was up after hearing the unmistakable sound of someone singing John Farnham's You're the Voice while microwaving a Chiko Roll at 2 am.
Strath man Darren Frente was discovered living as a possum inside a roof.
"He's got a nest made of Pizza boxes and old Centrelink letters and some milk crates as a makeshift lounge", said pest control officer Roy McCoy. "He hisses if you shine a torch at him. It's honestly impressive."
After 10 hours of negotiations, authorities decided not to remove Mr Frente after he urinated on some pink batts as a sign of dominance.
"He's not hurting anyone," said Mr McCoy. "Frankly, he's more well-behaved than actual possums."
Bendigo Council is now considering re-zoning the property as a protected habitat for marsupials.
Mr Frente now lives on a strict diet of apricots, bin scraps and free wifi.
