O.k maybe it was close to the 12 month law, in my case, it was 6 years ago . so you agree Claire bear, that the IDP must be valid to drive in HK, you cant just drive in HK without an IDP married to your licence, which was my original point, and my legal understanding, with a ful Australian drivers licence.
Thank you Ontheroad, for that piece of useful info, as I know you have lived in France. So, a HKSAR licence is valid there, just like it is for US and UK citizens. Last time we were in Paris, we were driven around by familiy, this time i will drive .
