Hi jetsetkiwi,
I was there a couple of days ago, and there is no wifi (but there are 2 computers & also a space for you to plug in your own laptop between these 2 pc's).
And no, currently no plans for their own lounge in CHC. I once asked & was told they would only do it if it went to 2 flights a day or more - and I can't see that happening anytime soon.
