Well I wasn't expecting that! Did a quick swing by to the Outback Aviary and to my total amazement a Wombat - I visit most weeks and this is only the 2nd time I have ever seen one out. It is Albert the male - I took a quick shot on my phone too where I could see his 'kit' so will post that in a mo.
