The best I can give you is "not any time soon". The next project is opening next year, and that is the Australian Walk-About. The Zoo and Safari Park generally alternate exhibit opening years (like Koalifornia in 2013 then Tiger Trail at the Safari Park in 2014 then Leopards of Asia back at the Zoo in 2015), so I'd say, factoring in fundraising time, we're looking at about three and a half years until we see anything happening at the Safari Park aside from Australia, unless they break habit and open something in 2019 too.
