A Perth vegan has taken her neighbours all the way to the Supreme Court, demanding they stop smoking, bouncing balls and even cooking barbecues in their backyard.

Cilla Carden from Girrawheen, in Perth’s northern suburbs, said she is fed up with the smell of meat cooking on the barbecue next door.

“They’ve put it there so I smell fish, all I can smell is fish. I can’t enjoy my backyard, I can’t go out there.”

Ms Carden, a massage therapist, is also furious at cigarette smoke wafting into her yard and the sound of children playing with basketballs next door.
