Bamboo didgeridoos are indeed traditional, the oldest known didgeridoo specimens are made from bamboo, albeit from an Australian native bamboo species
Bambusa arnhemica. Here's a thread on the forum about traditional bamboo didgeridoos:

There isn't a special term for bamboo didgeridoos as far as I know. Although the name "ebroo" was recorded for early bamboo didgeridoos collected in the Cobourg Peninsula region, the name is likely to have been used for didgeridoos made from all types of materials. The same can be said for "yi
daki". Yolngu may use it for instruments made from stringybark, as they might for instruments made from bloodwood, teak or PVC!
If you listen to the commentary on the latest YouTube video I put up, you can hear someone from Ramingining refer to David Dharrapuy as a "bamboo man" at around 3 mins 35 sec:

Oops... I just realised I deleted a post accidentally, sorry
I do not think that the word "bamboo" has been in use among Aboriginal people of the Top End for a long time, it is more likely to have come into usage through European contact (post 1788) rather than Indonesian contact. I would guess that the word "bamboo" began to have currency in the Top End beginning in the 1900s, probably from the 1950s onwards.
