They had one of the most tumultuous relationships on Love Island Australia this season.

But now that Cassie Lansdell and Luke Packham have both been dumped from the villa, their relationship seems to be back on track.

On Saturday, the genetically-blessed pair couldn't keep their hands off each other during an afternoon date in Sydney's Centennial Park.

Seemingly unperturbed by whoever could see them, the young couple kissed and canoodled on the grass as they soaked up the warm summer sunshine.

At one point, Cassie, 27, crawled on top of Luke, 26, before passionately kissing him.

Luke later returned the favour, getting on all fours over Cassie before leaning down and resting his head in her lap.

They were both dressed casually for the afternoon date, with blonde beauty Cassie showing off her tanned legs in a pair of tiny white shorts.

The tattooed stunner matched her shorts with a white button-up T-shirt and sneakers and accessorised with a black Gucci handbag.

Making sure that he was perfectly matched with Cassie, Luke also wore a white T-shirt and sneakers.

Despite their many ups and downs in the Love Island villa, the pair hinted that they could continue their romance in the real world after they exited the show last week.

In an interview with host Sophie Monk, the couple categorised their relationship as 'friends with benefits'.

However, Cassie has also hinted that she could be keen to pursue things with her Love Island fling Phoebe Thompson.

In an interview with 9Now, the blonde confessed: 'Hopefully Phoebe and me can meet up and see where it goes.'

She added: 'If something came from that and there was still a spark, then yeah I definitely would explore it.'

While Luke is now pursuing love with Cassie in Sydney, his twin brother Josh is tipped to win Love Island.

Josh and model Anna McEvoy have become fan favourites on the reality show, with many predicting that the pair will easily take out the $50,000 cash prize.
