Who does the music and is there anywhere I can get it? (not on youtube)

I love Masterchef Australia. Love the contestants and the judges. But I also love the music. Not the Katy Perry song at the beginning but the score played during episodes, specifically during high moments after cooks. And specifically during the last two seasons. (I've seen the first couple seasons years ago but am now presently working my way backwards.)

The music is highly manipulative but undeniably great.

doo-doo-da-doo, doo-doo-da-doo
