Where did you find this image?

Ok, the shop I'm referring to is called WallCandy & they have a branch in Sydney. Here are the details: Address:2 Danks Street, Waterloo 2017 Phone:(02) 9331 5884 Email:sydney@wallcandywallpaper.com.au

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.

Those seem to be trademark varieties from outside Australia. You could contact Daly’s fruit or Diggers Club to see what dwarf varieties there are available in your area.
