The UK CAA don't recognise anything. If you have a FAA ATPL, you would still have to do 13 exams!
Regarding your specific question. This topic has been discussed at length already so search away.
That being said. Most countries (except UK/JAA member states) recognise the ICAO ATPL but have bridging requirements and aeronautical minimums (hours). In Aus, I think its one (or possibly two) exams (air law, etc) and if you pass those and have >1500 hours helicopter experience & valid Aus medical, you've got yourself an Aus ATPL(H). The aircraft type ratings on your FAA licence should be converted to your Aus licence.
Hope this helps.
