Not much at all, sadly.....
Aardvark
West Indian Manatee
Rodriguez Flying Fox
Seba's Short-tailed Bat
Swamp Wallaby
The
only reason I've voted 2-1 Taronga rather than giving it a clean sweep is a) the two bat species and the aardvark are held in the Bush, which is the best tropical house I have visited and b) the manatees are in the Mangrove, which is equally excellent..... and given the fact that these are very subjective opinions based on just how much I like those two exhibits, I freely admit that Taronga probably does deserve a clean sweep
It doesn't really help Burgers' Zoo's case if you ignore over half of the species that count for this challenge.
The complete list is as follows:
Aardvark
West Indian Manatee
Rodriguez Flying Fox
Lyles' flying fox
Seba's Short-tailed Bat
Swamp Wallaby
Capybara
Merriam's kangaroo rat
Hispid cotton rat
Cactus mouse
Variegated rock squirrel.
Nothing on the level of Platypus and Long-beaked echidna, but from a European perspective still a some high quality species in some very good enclosures.
Both Flying fox species as well as a bachelor group of the Short-tailed bat are free-ranging in the 1.3 hectare Burgers' Bush rainforest. Together with Masoala & Gondwana easily the best "enclosures" for these species.
The Aardvark also live in the Bush and have a non-spectacular medium-sized enclosure. The move from the old nocturnal house to the Bush did the Aardvark really well and in the past 30 years over 30 Aardvark were born in Arnhem and nowadays one-third of European aardvarks were born in Arnhem and their genes have even spread to the US (Detroit).
(enclosure continues somewhat further around the corner)
This is the separation enclosure, mostly used when there are young, currently connected to the main enclosure
The Capybara also live in the Bush and nowadays it is a successful breeding pair with a smallish land part, but a huge pool, as they can also fully use the former Manatee pool:
Most rodents are kept in the Desert and about 20 years ago Burgers' Zoo was the first zoo in Europe to hold Merriam's kangaroo rat, a species which is bred very regularly behind the scenes. The same goes for the Cactus mouse and Hispid cotton rats, which have large breeding groups behind the scenes. The Rock squirrels are just a pair and no young were born recently. All four N-American rodents are huge rarities in Europe.

Cactus mouse enclosure
The Swamp wallaby are kept in a large standard grassy enclosure and are regularly breeding. Back in 2003 Burgers' Zoo was one of the first zoos in Europe to switch from Red-necked wallaby to start with this species.
Back in 1989 Burgers' Zoo was also the 3rd zoo to keep Caribbean manatees in Europe, when 1.1 animals came from Nuremberg, a male from Artis soon followed, but only the brother-sister Nuremberg pair ever produced young. In 2017 the animals moved from the suboptimal enclosure in the Bush to the Mangrove, where they have a one million liter enclosure, shared with a large variety of Central-American cichlids and other fish. It is easily the best Manatee enclosure I have seen and based on pictures it also compares favorably to other enclosures in Europe (but Beauval may surpass it next year). With a new female arriving in 2017, the enclosure was apparently approved on as in 2019 a calf was born.
I won't pretend Burgers' Zoo can win from Platypus and Echidna, but it is not that bad either, 2-1 to Taronga for me.
