Our giant Australian map stretches 50cm from WA to Qld/NSW. We also sell this puzzle blank, so it can be decorated any way you want, but just in case you'd like it done for you: we have hand painted the base a lovely forest green and glued red sand on the red centre!
The sand may come off a little here and there over time, this is the nature of the product and not to be seen as a fault.
In addition to providing a guide to where our Red Centre actually is, it also helps with putting the puzzle together whilst learning where the states of Australia are.
Furthermore, it can serve as a base for a small world set-up.
