For next time there are little wall repair kits from Bunnings which include special netting with a slightly sticky back. You trim it to size with a little overlap at the edges and stick it over the hole. It gives the layers of putty something to grab onto.

Apply the putty in really thin layers with the spatula scraping it as smooth as possible, letting it fully dry and sanding it flush before the next one. Sand it really flat with sandpaper around a foam sanding block because doing it with sandpaper on your fingers can leave it uneven.

For the paint it really helps to cut a 50c piece sized layer of paint from somewhere really hard to notice of the same colour (use a razorblade and kind of slice at an angle) and get it put through the paint matching machine at Bunnings.

Use a roller not a brush because you don't want visible brushmarks. Bunnings sell little disposable rollers and paint trays. Do really thin layers too with drying between, feathering the edges out with the last tiny (barely any) bit of paint left on the roller each time so it's harder to see a sudden transition. Putty and paint the sneaky spot you nicked the chip from too.

The paint colour you got mixed may differ slightly from the main spot due to different rates of fading (ie if the sample paint chip was taken from inside a wardrobe) but do your best, let it fully dry and rub a dusty rag over it at the end so it doesn't look too new.
