First the kiss, now a song for Shorten

Bill Shorten may have copped a kiss in Adelaide, but now he's snared a serenade in greater western Sydney.

The Labor leader took his campaign to woo voters from the streets of South Australia to the pavements of Campbelltown on Wednesday.

Ester Arador stopped Mr Shorten and shortly after introducing herself as a singer broke into a melody at the opposition leader's encouragement.

She sang Unchained Melody, the much-covered 1955 hit song which most prominently featured on the soundtrack to the Hollywood flick, Ghost.

"Oh, my love, my darling, I hunger for your touch," she sang, as Mr Shorten watched on.

The Labor leader appeared gleeful his daily street walks were proving a hit, after Tuesday's kiss on the lips from Adelaide resident Margo Carey.

"You might have just topped Adelaide yesterday," Mr Shorten replied.

Later, Ms Arador couldn't decide whether she liked Prime Minister Malcolm Turnbull or Mr Shorten more.

But she said she'd definitely vote Labor as long as Mr Shorten attended her next performance.

Chilean migrant Soraya Aravena Silva was keen to dispel claims immigrants risked welfare dependency, in an apparent response to Immigration Minister Peter Dutton's comments.

"You are here working, never dependent on Centrelink," she told Mr Shorten.
