BBC Nature Documentaries

[Kirben]

Are many of the BBC nature documentaries still released locally? or just the major ones (i.e. Blue Planet / Planet Earth) now?

I noticed many were released on Blu-ray in the distant past, but not so many in the last few years. I just started collecting, and was wondering if it was worth waiting to see if more recent ones are released locally, since importing from the UK is so costly now.

On a side note, it seems like only Amazon (AU) still has Blu-ray releases of old ones in stock, they are no longer even listed in other retailers (i.e. JB Hi-Fi).
