Adam Hills is hilarious! He's been on Mock the Week a few times, that's how I got to know about him and decided to check out some of his stuff on YouTube- would definitely recommend people to do that. I meant to see him live a few months ago but I couldn't go because my friend I was meant to go with was ill that night. At first we only heard rumours that he was performing at a particular place but I wanted to be sure so I'd try my luck at sending him a message online. He replied a couple of hours later confirming he was performing at the venue and said he looked forward to seeing me there. Thought it was nice of him to reply in the first place since I wasn't really expecting it! He does tour around UK doing festivals e.g. Edinburgh Fringe, Reading and Leeds Festival as well as London venues. I hope to catch him next time he tours around.
Another Australian comedian to look out for- Chris Lilley. He's not a stand up comedian. He's a comedic actor, known for his mockumentaries We Can Be Heroes and Summer Heights High. He's been compared to the likes of Ricky Gervais, Christopher Guest etc but he really is his own person and is very talented! He fully immerses himself in all the characters he plays including a teenage girl, an unruly teacher, a drama teacher etc. Plus he gets involved with everything in the shows he makes- writing, producing, directing, acting, singing, dancing, composing music etc. Well writing about him won't do him justice, I would just recommend that people give his shows a try
