I visited today. I do not think they have any camel, but it's always possible there are either some off-show or in one of the huge drive through paddocks, where it seems they could easily wander out of eyeshot.
(I just checked the tiny map on the ticket and there is a picture of camel in the desert drive-through section, so it's possible I missed them. It was a fairly eventful day, so my mind wasn't really on the ball. As far as I could see that Desert Area only contained llama and a single kulan.)
I will write a brief account of my visit in the next couple of days, as the whole day was fairly ridiculous.
