That happens pretty often, actually. For example, if the BBC in the UK records the audio descriptions, it doesn't license them to international broadcasters. International folks either have to due without, or record there own. ABC is probably similar. I suspect it has something to do with the contract they sign with the voice actress who reads the AD. She'd probably be owed international royalties if they broadcast it outside of the country. I can't really point fingers: CBC audio describes all programs inside Canada. But just like everyone else, CBC programs don't seem to have AD in other countries.
Edit to add: and movies, too. I remember watching a movie in Canada in theatres with AD back in the early days (10 or 15 years ago), and then watching the same movie later in the US. In the US, the AD was read by an entirely different person, using a different script.
