Yes, the masterplan outlines the following:
- Giraffe, zebra, ostrich and guinea fowl housed together
- A new giraffe house
- An expanded meerkat exhibit that runs parallel to a kid’s playground with tunnels

All pretty generic stuff, though to be fair, the general public are more excited by these species than antelopes. I agree an open range sister zoo would be a real asset to Perth Zoo and enable them to focus more on rainforest species; while reducing megafauna.
Interestingly, the masterplan concept art implies an adjacent exhibit for bongo, but I can find no recent mention of this species in the masterplan. They were originally mentioned years ago in conjunction with Indian rhinoceros as a FAQ of what could replace the elephants. It appears these ideas have long been revised.
