This is hard to find in AU LED projector with very short distance from screen to throw image.
Price via link is £899 without delivery and taxes, however it drops to another value in cart due some promotion.
Domayne and Harvey Norman have it for AUD2300

The LG PF1000U is in a class by itself. You might think of it as a portable 80" flat panel TV. It weighs under 5 lbs so you can take it anywhere. It is ultra short throw, so you sit it next to a wall and project high contrast full HD 1080p images up to 100" diagonal. It has a built-in VHF and UHF TV tuner and some smart TV apps like Netflix, VUDU, and YouTube, so plug it in and you're in business with a flat screen TV replacement.
The picture quality is gorgeous when viewing in a dark room if the screen image is not pushed too big. At 60" diagonal it absolutely sparkles, at 80" it solid and engaging, and at 100" it is lower in contrast, but still quite serviceable. We wouldn't push it beyond that. LG is correct to state in the specs that the PF1000U is for images in the 60" to 100" range. And keep in mind when ambient light is introduced the contrast fades noticeably, particularly at the larger screen sizes. If you plan to watch in a room with indirect ambient light or a lot of white, reflective surfaces, you are better off staying in the 60" to 80" range for image size. All projectors look better in the dark, and it is especially true of this one.

I considered projectors a while back and the gradual drop in 4K prices changed my mind as projectors are like my Mrs, they both need a lot of factors to be just right else it doesn't work out :)
Waiting for a decent 75 inch 4K to drop below $2K
