Anna Goanna
Background
Anna Goanna is a resident of the Crack in the Earth. She escaped with a group of refugees from Sydney before the bombs fell.
During the events of Mad Max Beyond Thunderdome (1985) played by Justine Clarke
Savannah Nix is walking in the desert when she finds Max and drags him on a sled to the Crack in the Earth. Finn McCoo runs to Savannah and she tells him that she found Captain Walker. Max is brought still unconscious, to the center of the camp and is surrounded by The Hunters, The Guardians and The Gatherers. Mr. Skyfish tries to contact Mr. Walker and Gekko and Anna use a record attached to a stick to try and contact Max with sonic. Scrooloose pulls the string on his talking Bugs Bunny doll and then hugs it. Savannah cuts Max's hair and he eventually wakes up. Slake tells Max that they are the waiting boys and they have been waiting for him. Savannah then tells Max the story of the Lost Children, who were in a plane with adults who fled when the bombs started to fall. The plane eventually crashed due to turbulence and the surviving children were told to wait by the adults who left with Captain Walker to get help. Max tells them that he isn't Captain Walker, but they insist he is and take him to a plane half buried in the sand. Tubba Tintye tells Max that they are ready to go, but Max just walks away. Later, Savannah bangs a gong and asks the others, who is with her to leave. Anna reminds Savannah that Max was almost dead when Savannah found him and Max tells them about Bartertown and that there is no Tommorow-morrow Land. Savannah continues to leave with some of the children and Max grabs Slake's staff, which is actually a rifle and shoots it towards Savannah, she throws her spear in between Max's legs and he walks up to her and knocks her unconscious.
In the morning, Anna wakes Max up and tells him that Savannah, Mr. Skyfish, Gekko, Scrooloose, Cusha...the pregnant girl, and Finn left in the middle of the night. Slake tells Max that Savannah and the others have been gone for half a night or less and Max prepares to go after them with Anna. Anna tells Slake and Mr. Scratch that they will need a Hunter and Tubba Tintye is nominated. Max, Anna and Tubba head out into the desert and Eddie runs up to them in order to join them. They eventually find Savannah and the others, who are being pulled into quicksand. They manage to save most of them, but Finn and Gekko are killed. Scrooloose sees lights ahead and Max tells them the lights are from Bartertown. They sneak into Underworld in order to rescue Master who is being guarded by Ironbar and a pair of Bodybuilders. [[Pigkiller[[ sees Eddie and laughs and Ironbar sees Scrooloose, who is sitting above him, motioning to the others. Mr. Skyfish swings on a rope and saves Scrooloose and Monkey and manages to knock one of the Bodybuilders into the pig pen. Ironbar starts shooting at Max and the children and Pigkiller uses a shovel to knock the other Bodybuilder unconscious before using bolt cutters to free himself and Master. Master uses a grain chute to knock Ironbar unconscious and Blackfinger walks in, but quickly runs away when he sees Max and the children. Max runs after Blackfinger, but then runs away when Blackfinger returns with a large amount of Aunty's Guards. Pigkiller gets inside of a truck on train tracks and tells everyone to get inside. Max and the children get inside the truck and Pigkiller starts it and drives it away, causing parts of Underworld to collapse and explode.
Pigkiller continues to drive along the track and they are followed by a large convoy consisting of Aunty, Aunty's Guards, Ironbar, Fur Trader and Cowboy. Max shows Anna and Mr. Skyfish how to use the record and puts Gekko's record on the record player. Aunty and her group attack the truck and attached train cars and Max is pulled onto the vehicle driven by Cowboy and punches and throws Cowboy out of the vehicle. Scrooloose jumps onto a vehicle driven by one of Aunty's Guards and repeatedly hits him in the face with a frying pan. Ironbar shoots a harpoon into the truck, impaling Pigkiller in the leg and Max rams the vehicle with Ironbar in it, causing it to crash and leaving Ironbar stuck on the front of the truck. Aunty Entity, one of Aunty's Guards and Blackfinger jump onto the train cars and try to grab Master, who is saved by Savannah. Ironbar tries to grab Master and Max kicks him onto a train exhaust pipe. Ironbar motions for Fur Trader to help him until Fur Trader's motorcycle hits a concrete curb and he flies to his death. Mr. Skyfish uses a hacksaw to cut the pipe Ironbar is hanging from and the truck comes to a halt in front of a berm. Jedediah Jnr. tells them that it is a stick up, but runs away when he sees Aunty and her group driving towards them. Max and his group run after Jedediah Jnr. who runs to Jedediah. Max tells Jedediah it is his lucky day and his plane will save his life. Everyone gets into the Flying Jalopy, but as Jedediah is driving it forward, he tells Max that they are overloaded and there's not enough runway between them and Aunty's group. Max jumps out of the plane while Scrooloose drives up and gets into the plane. Max takes the vehicle Scrooloose drove in and drives it straight towards Aunty's group, killing Ironbar and many of Aunty's Guards. Jedediah then flies the plane to a destroyed Sydney.
Many years later, Savannah tells a group of people of their origins and how they must keep the lights on so others can find their way home.
