She’s in the midst of touring her latest album, underrated gem No Shame.
The singer, 33, showcased her toned figure in a two-tone bikini, donning a bright yellow bandeau top and black bottoms.
Lily’s mismatched swimwear was set off with a quirky sailor style cap and a pair of round shades.
The group were seen lounging around and chatting during their leisurely outing, making the most of the natural beauty the island has to offer.
Lily was in high spirits as she relaxed with her pals, later heading off on a bike ride to explore the local area.
The singer is currently wrapping her No Shame world tour with performances in Melbourne and Perth.
Lily also shared some Instagram shots from the same trip, enjoying a swim close to the remote island’s sandy shore.
Evidently in the mood to relax ahead of her final show on Australia’s west coast, Lily enjoyed a beer while taking in the breathtaking scenery.
Giving her latest set of Instagram images a playful caption, the singer – who will return to the United Kingdom after her final show on February 12 – wrote: ‘Rottnest Monster.’
Lily completes her tour having waded into the controversy surrounding actor Liam Neeson while performing in Sydney.
The Taken actor, 66, faced backlash after admitting he once felt a ‘primal urge’ to ‘murder a black b*****d’ after a loved one was raped.
Lily later addressed his comments on stage by calling the actor a ‘racist pig’, several concertgoers claimed on Twitter.
The Smile singer finished off her second performance in the New South Wales city with F**k You, a track from her second album It’s Not Me, It’s You.
She introduced the song by saying: ‘Usually, I dedicate this song to Donald Trump, but today I thought “I feel more disgusted by Liam Neeson”. So this is going to be dedicated to Liam.’
According to a review in The Courier-Mail, Lily went on: ‘Everyone went, “how dare you call Liam Neeson a racist!” I was like no, how dare Liam Neeson!’
‘How dare Liam Neeson go out with a weapon looking for any black bastard to kill for something that was completely unrelated.’
It’s clearly she enjoyed her tour!
