It looks like the one Charlie Albone did was a plastic screen (Bunnings) adhered to a mirror. Im not certain what type of mirror he used. You might be able to find large acrylic mirrors through plastic suppliers. These would be suitable outdoors.

Either of these suitable? Both companies are in Victoria. http://amonsonlighting.com.au/axo-lighting-spillray-pendant-light-6-lights.html http://www.davolucelighting.com.au/Torino-6LT-Round-Pendant-Axolight-Spillray-Pendant.html This one, Western Australia. http://www.alti.com.au/products/spillray-6-light

This isn't a personal recommendation as I have not yet purchased anything from this company, but I've been admiring the timber floating shelves on their website. https://shelvingshop.com.au/product-category/floating-shelves/wood-effect-finish/ Or you can buy the brackets and have the shelf custom made in whatever material and size you want. https://shelvingshop.com.au/product-category/brackets-2/floating-shelving-brackets/  I think hardware stores also sell brackets by themselves. I was thinking of going the custom route because that means I can ensure the brackets will be attached to the studs. I believe you can paint melamine after proper preparation of the surface, but I doubt if you can stain it.
