West Midland Safari Park

That is a very serious and expensive looking fence for a wallaby!

I'm guessing this is a monkey-proofed fence? Did they keep the monkeys and the wallabies together?

This used to be part of the rhesus macaque enclosure but they no longer have any primates in the drive-through section.
To be honest most of the fences at WMSP are quite intrusive and bold like this, not the greatest look in the world if I'm honest and it sort of ruins the safari experience if you're in to immersion.
