Duck for Cover is an Australian performer's association that arranges cheap insurance for its members, including for fire performers. (Annoyingly, they don't include workshops.)
Relevance to Poms? You could join as a Pom living in Oz, and it covers working overseas (apart from US/Canada), but you have to live in Australia to join. Closest name I could see in a UK search was blokes clothing called duck AND cover.
Also Skully, the link on your post to an answer doesn't work.. goes back to the forums 'title page'.
