Katy Perry's Prismatic Tour hits Australia as the "Roar" singer wowed the audience with colors and her powerful voice.

The 30-year-old "Thinking of You" singer, who has been on a world tour for the past six months, landed first in Perth for the Katy Perry Prismatic Tour in Australia.

The singer belted out her chart-topping hits like "Roar," "Teenage Dream," and "Fireworks" in the two-hour long concert.

Meanwhile, her adoring fans, who waited for the performer, were stunned by the colorful set of the Katy Perry Prismatic Tour concert. It was designed with rainbow lights, the Daily Mail said in a report.

The "Roar" singer, who recently celebrated her birthday, emerged from a prism nestled at the center of the stage, while people screamed and shouted.

The performer's show-stopper moves were backed-up with dancers dressed in soldiers' costumes, a report from Perth Now said.

The costume change through out the concert is another point of interest.

During one performance, Katy Perry rocked a space-suit silver two piece while her hair was braided in a pony tail.

In another song number, the singer performed in a fairytale-themed dress while she donned a curly blond hair wig with streaks of blue, yellow and pink.

But the loud noise and the bright lights were halted in the middle of the concert as the "Teenage Dream" singer emerged on the stage with only an acoustic guitar and several back-up singers as she sang some of her mellow hits.

Katy Perry will be spending the rest of the year in Australia for a series of tours as she is also set to perform in Adelaide, Melbourne, Sydney and Brisbane.

Before heading to United States for Christmas celebration, the pop diva, who is rumored to be dating DJ Diplo, will also perform in Auckland, New Zealand for two days.
