Phoebe Tonkin thinks her new TV show Two Years Later shows the "complexities of navigating relationships" in your 30s.

The actress stars alongside Brenton Thwaites in the new Paramount Plus series about a couple whose fledgling romance is cut short by the Covid-19 pandemic, with fate reuniting them years later for another chance to make their relationship work.

Reflecting on the lessons she hopes viewers will take away from watching the show, Phoebe told The Au Review: "I think this show does a really good job of showing the complexities of navigating relationships and coming into a relationship with all this baggage.

"You've lived a life. Especially being in your 30s, by the time you meet someone, it's bringing that in and learning to love yourself and the person that you're falling in love with at the same time."

Phoebe also reflected on whether or not the two characters would still be together if the pandemic had never happened.

She mused: "Ooh, I don't know. I think we definitely explore in (the show) is this a sort of destiny. I think they probably would have.

"When they do meet, unfortunately for my character, she isn't entirely…well, I don't want to spoil anything, but if you believe in true love, as I do, then I think these characters were destined to be together at some point."

With Brenton adding: "That's a great question. Maybe not? Maybe it took Covid for them to both realise, 'I really like this person.'

"Maybe they would have, and it's love at first sight, if you believe that stuff. Obviously we all went through Covid… but it's about reconnecting with people. And not even romantic, just people."

The series shows the pair having a series of dates two years down the line to determine if their relationship is meant to be.

As for which date is most important for the couple, Phoebe said the one where they "go back to Emily's family's house".

She explained: "It's a really vulnerable episode for Emily, and it reveals a lot about how she approaches relationships. It's one of my favourite episodes."

While Brenton added: "First date. First episode. I think it's a defining moment in the show. It's the opening scene. I think because they've known each other for so long, we can all relate to being in our 30s, and he's thinking about this woman for a long time, so he decides to just really commit. He goes for it.

"And it's either stupid or ballsy. I don't know yet. It's these two people being vulnerable and open towards each other. It's a beautiful thing to watch. When you see that and feel that…it can change lives."
