Austin begins attending SMS shortly before #6, Kristy's Big Day, when he goes to the Final Fling dance with Claudia. In #10, Logan Likes Mary Anne!, he goes with Claudia to the Halloween Hop and the party at Stacey's house. At the party, he is seen throwing pretzels into his air and trying unsuccessfully to catch them in his mouth.
In #52, Mary Anne + 2 Many Babies, Austin pairs with Stacey for the "Modern Living" parenting exercise.
He is in Claudia's English class.
