@vignouse well going by his size/weight he is mature, and looks to be around 7kg maybe a little more. so that would mean he is likely to be at least 3 years old. the only way to actually tell a koalas age is by the wear on their teeth so he could be 3 or he could be 13. I've been fooled before thinking a koala was quite young looking only to discover by teeth they were old. I haven't seen his scent gland either which would give me some clues on how young he is not so likely to be - if he has a big well used smudgy gland he is likely to be 4 or older. Good question - not so easy to answer!
