In the late 2000's Melbourne zoo also lost Jaguars, European Badger, Asiatic Golden cat and others mainly in it's carnivore section.
Possibly more.
I don't know much about the 2000's for Melbourne zoo but I do know they lost a number of animals as stated on the Exotic Mammals thread and possibly birds and reptiles as well.
I researched more into this and it's worse than I thought. Evidence can be found within the zoochat gallery or on this thread or the Melbourne news thread. Also the big/small cat thread.

Central American Wood Turtle (seen in my 2019 visit but no note of it in my 2020 visit or visits by other zoo-chatters).
Tinnemeh Grey Parrot (Signed for a small portion of time then sinage was removed, I know
@WhistlingKite24 saw these in late 2018 but I don't think anyone has seen them since)
Not including off displays, unsures and question marks the total stands at just 2 new aquisitions with a whopping 44 phase outs. If you include question marks, unsures and permanent off displays the total stands at 4 acquisitions and 52 phaseouts.
Keep in mind this does NOT count species lost in the late 2000's so Jaguars, Temmicks Golden Cat and European Badgers have not been included on the list.
Native species don't fare much better, especially the reptile and bird collections, I might make a list on them if necessary
