Ed Newman (Ben Schumann) is the central character of the show. He spends most of his time with Tammy Lane who has been his best friend since they were five. It's revealed, they had made pact awhile back to lose their virginity to each other if they couldn't find anyone else to do it with. Ed has also been friends with Luke Gallagher since they were kids, but they began moving with different crowds a few years back. Ed is a geek who develops a crush on Scarlett Carlyle when they first meet at her father's hotel where Ed works. He is very socially awkward, and is quite embarrassed about being a virgin for the first episode, but remedies the situation with his neighbour, Philippa, early on. After trying to get a fake I.D and getting caught, he finally gets into notorious club "Duck Duck" after Eva steals an I.D and Ed, posing as a transgender woman, gets let in. Upon entry, he spontaneously kisses his boss from the catering job he did earlier that day, sparking a real kiss between them. Eva sleeps with him after he gets depressed because he kissed a man and he tries more than ever to fit in with the crowd. In episode 5, he begins to like Eva after their one night stand and he is not sure how to approach her. In episode 7, Scarlett kisses Ed as a goodbye present for leaving the gang unexpectedly. In episode 8, Ed loses a chance of getting a car and he says to Phillipa, "fucking you was the worst mistake I ever made!". Which prompts her to show the video of them having sex to the whole mall as revenge for him being mean to her. When Tammy sees the video, she angrily punches Ed in the nose and their friendship is strained a bit. In episode 10, he admits he loves Tammy and has sex with her at Luke's house, then finds out Tammy later on sneaks out and has sex with Luke. Ed is extremely preoccupied with sex and being cool, which leads him to do terrible things to his friends in the name of achieving it.
Tammy Lane (Gracie Gilbert) is Ed's best friend, a perfectionist and hard worker. She's considered the "mom" of the group as she's the most responsible and careful. She has an eccentric dress sense and is an aspiring music journalist and frequents music gigs in the Valley. She initially dislikes Scarlett, as she's the complete opposite of her having labelled her a "troll" in the first episode. Tammy is frequently thought of as a stereotypical good girl, but occasionally attempts to break her image. She has a budding crush on Luke as he finds he also has one for her and their relationship progresses throughout the season. With her opening up more, she finds that she can accomplish anything that she sets her mind on, if only she were as confident as Scarlett. Episode 4 finds Luke getting jealous at other men watching her as they both work at a party, her being labelled a "prostitute dressed in lycra." They end up in the club and finally get together, much to Scarlett's jealousy. In episode 6, she breaks it off with Luke after she finds out he had sex with Scarlett on her couch in episode 3 and in episode 8, she exclaims her love for Ed, only to be rejected. In episode 10, she wants to lose her virginity after school is over, she then goes to Luke's house and loses her virginity to Ed, after he says he loves her. She later sneaks out and ironically has sex with Luke after he also confesses he loves her too and Eva catches them.
Scarlett Carlyle (Emily Robins) is a fashion-conscious, spoilt girl that lives in a fancy hotel. Originally from Melbourne, her mother sent her to live with her father at Urban Hotel in Brisbane due to her troublesome behaviour. Being that her father is constantly busy with work, she feels that she must be bad in order to get any attention from her father. After meeting Ed in episode 1, she arranges a birthday party for him, telling him to invite heaps of popular people. When everyone arrives, Ed and Tammy are nowhere to be seen, the party gets out of control after Luke texts everyone he knows to join them. After a burning lounge chair falls off the top of the penthouse building in the hotel, she gets into a heated argument with her father. Episode 3 finds her trying to vie also for Luke's attention, but she sees that he is infatuated with Tammy instead and continuously tries to get him to pay attention to her. In episode 7, after she gets expelled from school she makes the gang spend the day trying to make her happy as a goodbye gift. It's revealed that as popular as she seems, she never really had true friends back in Melbourne and the gang is all she has. Simultaneously, the gang realises that Scarlett is the reason why they're such a close knit group of friends as she's the one who brought them all together. Later that day she blackmails her parents into letting her stay with her dad at the hotel after she finds them in bed together. In episode 9, she's seen to be actually studying for the exams.
Eva Lee (Adele Perovic) is a rebellious tough girl with pink hair and an "eff you" attitude. Known to be a lone wolf, she finds comfort in her graffiti art all over Brisbane. Known for rebelling against authority, she speaks the truth and doesn't hold back. She first meets Scarlett in detention and later burns the word "sanctuary" on the school grass. After spontaneously sleeping with Ash (whom she met in episode 3), she finds out that she isn't as tough as she thought and that her new-found friends may be exactly what she needed all along. In episode 6, she thinks she's pregnant and travels to a music festival to find Ash. Later on, when she gets her period at the hospital, she sadly ends things with Ash. Eva is adopted and in one episode met her biological brother and was close to meeting her birth mother, but ended up not wanting to. Although she loves her adoptive parents, she constantly feels pressured by them to stop graffitiing, and be more serious by pursuing a professional lifestyle in the medical field. She later disappoints them when she skips the exam. In the last episode, she catches Luke and Tammy having sex. She's last seen driving her scooter on a highway.
Luke Gallagher (Brenton Thwaites) is the cool attractive surfer guy that everyone wants to date. After meeting Tammy, he finds that he is deeply attracted to her. Not feeling anything like it before, he is unsure how to approach her as she is very different from the girls he's used to. After getting jealous of other men staring at Tammy at a party Ed, Tammy and himself worked at, he realises that he can't let any opportunity slip through his fingers and begins to open up to her more. While in the infamous "Duck Duck" night club, he kisses her after much sexual tension throughout the first few episodes. Luke's parents died when he was younger and he lives with his serious no-nonsense older brother, Dylan, a firefighter. In episode 9, he got in a car accident and suffers a concussion. Later when Ed chickens out at the exam, he writes Ed's name on his own paper out of generosity. In the last episode, Dylan tries to sell their house much to the dismay of Luke. When a man claims Dylan owes him a debt, and holds his friends captive in the house, Luke reveals Dylan has a gambling problem and probably wanted to skip town to avoid paying his debt. Luke then makes Dylan take the house off the market and implies the gang can be his new roommates. He later confesses he loves Tammy and has sex with her, not knowing she just had sex with Ed.
