The 20-year-old pop star was spotted soaking up the sun on Wednesday while meandering through Sydney’s picturesque harbour.

The Ocean Eyes singer looked every inch the rock star in a black jacket, jeans and black boots as she boarded a boat with her brother Finneas O’Connell.

Billie let go of her raven hair and completed her look with a black cap and brown shoulder bag.

Billie had clearly been preparing for her outing, as she was carrying a distinctive water bottle and black backpack.

Meanwhile, older brother Finneas O’Connell, 25, wore a satin bomber and chinos for the outing.

Her day trip to Sydney follows Billie admitting that there is one thing she absolutely adores in the Land Down Under.

She told Fitzy and Wippa of Nova FM on Wednesday that she loves native Australian sounds and even samples them in her music.

Billie, who was famous for signaling a pedestrian crossing in Sydney for her breakout single Bad Guy, told radio hosts Ryan’Fitzy’ Fitzgerald and Michael ‘Wippa’ Wipfli that she especially likes the bird sounds of Australasia.
