Help with Australian wood carved paperweight

Hello everybody. I have this vintage wood turned paperweight. It is one solid piece. It seems to have a layer of lighter varnish and you can see where this has flaked off and you can see that the wood naturally has a dark colour. On the bottom there is a stamp that is partially indistinct (see the last image below). It reads "AUSTRALIAN _____ WOOD". I cannot read the middle word. It ends with the letter "A" and is 4 or 5 letters in total. Any help in identifying this word would be much appreciated (also any other information if you recognise this type of work). Many thanks.
