Ive been fined a couple of times for parking on the nature strip directly infront of my own house, by my local council. Call your council next time she parks there.
BTW each time I have been fined there has been no parking available anywhere near the house. we have all have steep blocks, and to top it off we have a narrow road with a lot of solid yellow lines. Its nearly impossible to fit a car driving down the centre of the road due to all the parked cars.
