Self-confessed "summer lover" Alexandra Sinadinovic is readying to take on 11 other girls from across the country during season nine of the popular reality TV series.

The 18-year-old, who waitresses part-time at a wedding reception centre, auditioned for the show in Chatswood and believes she can take out the competition.

"I want to be an international supermodel," she said.

"I've wanted to be a model since I was 12 or 13 ... I'd read Russh magazine and Vogue and I wanted to be in there ... it's all I want right now."

The teen lists her loves as the beach and animals, noting she would love to own a Great Dane dog.

She described her style as "grungy", born from op-shopping with her dad every Saturday morning.

"I love chokers and big chunky rings," she said.

"I don't feel like myself without boots ... I feel invincible with big black boots on."

The blonde beauty was looking forward to living with the other models, but believed they would get angry at her love of "singing a lot ... sometimes really loudly."

She follows in the footsteps of several other Illawarra girls who have made their mark on the model franchise.

Keiraville's Demelza Reveley took out cycle four of the series, beating fellow Wollongong girls Rebecca Jobson and Alyce Crawford for the title.

The latest series of Australia's Next Top Model starts on April 30 at 7.30pm on Fox 8.
