Went and watched a couple of mixed comedy shows - Best of Fringe UK, Best of Adelaide Fringe etc
It's not bad, none of the performers are big names, but it gives you the opportunity to catch a glimpse of someone you wouldn't otherwise see. Some are hilarious and others flop.
If you're looking for a cheaper comedy gig it's worth seeing Adelaide's own Micky D or former Adelaidean Ro Campbell.
