Please include the Southern Cross to symbolise we're in the southern hemisphere.
Circular in shape with a laurel wreath (like in the Trainer of the Year logo), an open book (Google Griffith University), a tree or tree leaves (preferably Eucalyptus leaves) and set-out as in the 'Learning to Learn' logo, i.e., laurel wreath, southern cross, open book and tree/leaves on one side of the design with 'AUSTRALIAN INSTITUTE OF ARBORICULTURE' on the other side.
Sorry everyone- the laurel wreath isn't working for me so can I ask it be excluded. Also meant to say the branding colors are black, lime green with a hint of gold if that could be worked in please.

Great artistic interpretation of the elements
