IIRC, you wanted to create a walk-thru habitat for your gliders?
Many Australian animals are nocturnal, so it makes sense to have night tours, but it is not always easy to convince people to head out into the woods at night. When Night Safari Singapore first opened in 90s, almost 70-80% of its visitors were tourists as locals didn't appreciate the idea of seeing animals at night. Only in recent years has the ratio of local vs foreign visitors evened-out a bit.
Yes we do want a walk-through, more so since seeing flying squirrels at Singapore Night Safari next year. I've got a couple of ideas, but it is a big commitment for us.
We do take private tours in with squirrel gliders, a great experience, but too difficult for general tours currently.
