This is the inside of the LA Zoo's Australia House which reopened in spring 2015 after being closed for many years.
It was built in the 1980s as the koala house and once housed the koalas, echidnas, and brush-tailed bettongs. When the zoo's koalas died the house was closed. New koalas came in the early 2000s and are now housed outside. This building was used for temporary exhibits of animatronic dinosaurs (2005?) and spiders (2007) and was closed after that.
There are two yards separated by a short fence. Brush tailed bettongs and echidnas live in the yard closest and the southern hairy-nosed wombat lives in the farther yard. Sugar gliders can use the whole space.
