It's a shame Melbourne demolished it. I feel like this was only done to prevent them from being stuck with such an exhibit long term that was very much a 'large cage'. It could've EASILY been renovated to make it more naturalistic looking eg. replacing the fencelines with newer fences, implementing viewing windows. Now we're stuck with a very underwhelming lion exhibit imo.
I gather that having a cage-like appearance is considered a drawback. Interestingly enough, early plans for Taronga's current lion exhibit imply that the glass viewing bay would have originally been meshed, and constructed further to the west, to give the impression of the humans being caged. While there can be glare at times in photos, I much prefer the finished product.
