List of Thank God You're Here episodes

Guests include various Australian personalities, usually with a comedy/acting background.

^ This is the first time there has ever been a tie between two winners in one night.

^Note: All the heroes' names and powers, plus the villain's name were coined by the contestants. (They were asked who they were and who the villain was)

^While Kate Langbroek and Akmal Saleh when through the door, Shaun Micallef and Angus Sampson went to two green rooms on both sides of the set, Frank Woodley headed into a helicopter outside the studio which then took him up above the studio to do his segment.

^ Contrary to popular belief, this was not the first time a member of the ensemble cast did not say "Thank God you're here" at the start of the scene. Lines similar (but not identical) to the title of the show have been used in scenes before, such as "Thank the Lord you're here" and "Thank the gods you're here". However, this was the first time the guest entered the scene without using one of the trademark blue wooden doors. Instead, Matthew Newton was escorted around the back of the set by host Shane Bourne, and he entered through a curtain (which, when viewed from the front, made him look like he was emerging from the car which was half-embedded in the wall of the set). The first words spoken were, "Thank God you're alive!"

+ For this final scene, Ryan Shelton was placed elsewhere (presumably out the back or to the side in the studio) with four kids who looked around 4–5 years old.

^ The first time that a Guest Performer says the line "Thank God You're Here". Josh Lawson knocked on the door as he was about to walk through and then when entering he quipped "Thank god you're here, I was knocking for hours."

^ Featured Australian personalities Alan Fletcher (Neighbours' Dr Karl), Kimberley Davies and Matt Welsh on the Miss Universe judging panel. This episode was also advertised as an 'international episode' that would feature a Turk, a yank, and two kiwis.

† Tony Martin went through the regular door but, had to be let in through a window by the ensemble cast members in the scene.

^ Jimeoin had to go around the side and crawl through to the scene.

^ Once again, Matthew Newton was led around to the back of the centre set, and started the scene coming down the emergency slide to appear like coming from the plane wreckage.

† Featured special appearance by Australian Idol judge Mark Holden.

^ Instead of opening the door, Julia went behind the set and was asked to wait for the doors to be slide open to look alike a "This Is Your Life" entrance. Featured special appearances by Play School presenter Simon Burke as the host and former Perfect Match host Greg Evans.

† Instead of opening the door, an ensemble cast member dressed as a SWAT officer smashes the door for Tony.

^ Kate entered via the back of the set to look as though she had come up some stairs within her house. This scene also featured Mick Molloy as a performer.

^ Instead of walking through the door, Sean entered via a children's tube slide which he slid down on into the set. Tom Gleisner said he would give Sean bonus points if he exited the scene the same way he entered - back up the tube. Shane Bourne told Sean to go ahead, but Sean said "after you", resulting in Shane climbing up the tube as well. This is one of the very rare times Shane gets involved with the set.
