Please put me out of my misery

What is that mo vie from i think 7 to 10 years back? It’s kinda like a fairy tale’esque vibe. A mother lives in a beautiful house with i believe lots of flowers. It’s in a rural small town i wanna say australia or new zealand but could be totally off with that. She lost her young daugter i believe she’s missing. The town kinda treats her like she had something to do with it. Sometimes she walks past a garden with a i wanna say aboriginal man sitting in a chair with a distorted face who talk to her. During the whole movie a plumber is mentioned to fix something in the kitchen. Now for the part that should help someone out there find it for me. a tape or recording is found in the kitchen cubboard on which it’s revealed that the daughter was playing in her bedroom while filming herself. Then you see the father come in and i wanna say accidentally kills the girl or maybe even tries abusing her…anyway the girl dies. There is this beautiful scene of her lying in a bad tub in a white dress surrounded bij blood, the director made it look almost like art. Also she eventually was buried in the woods nearby. that’s all i know PLEASE someone find this for me
