Definitely life savers when I was traveling in Australia and New-Zealand. These Arnott's cookies made up for my breakfast, lunch and often late night snack as well.
Very difficult to find outside Oz but colleague Niels found a link to a US webstore who have them:

A note of warning; many people who have tasted TimTams have become addicted to them and even have fights on the Internet about the similarity to the British Penguin cookies.
Anyway, feel free to get that well-known Christmas spirit and send me some TimTams...
