The big issue with phasing out elephants is that they are just too big of a drawcard (no pun intended) and all the other options are either not possible or are flat out underwhelming. As cool as orangutans are, there is the issue of the Skyfari as laid out earlier. Malayan tapirs are a phase-out species, Indian rhinos aren't in Taronga's vision for the forseeable future, nilgai and bonnet macaques are fine species on their own but are just way too underwhelming a replacement... I know Taronga's probably mentioned they weren't going to make the switch to being a bachelor facility for elephants, but I genuinely think that's the best option they can go with. I'd totally be fine with any of the other replacement options if the Australian government was OK with streamlining the import process as well as reversing the Malayan tapir trend.
I throughly agree here; although the only thing is Taronga only moved half their herd to Dubbo in the first place, to hold their bulls in a more larger, more suitable location. Especially after the Lucy Melo incident in 2012, i'm not quite sure they'll go back on their word. Then again, that incident was undertaken during free contact, and the bulls are managed now with protective contact.
I think the fact the simple fact that Taronga had to begin management via protective contact, then limited their breeding opportunities as their bull (Gung), lived in an entirely different enclosure at the opposite end of the zoo which required keepers to walk them there. Of course, with protective contact this could no longer be managed; so it seems Taronga eventually just gave up and shipped Gung to Dubbo. At the time, Pak Boon, Tang Mo and Jai Dee could've been sent to; which would've been the best choice. But obviously Taronga believed either a) they could maintain the program at Taronga via AI with Pak Boon or b) Jai Dee was Pak Boon's last designated calf anyway, before she was removed from the breeding program due to TB.
