On Tuesday, the couple looked as loved up as ever as they hit the beach near Byron Bay for an ocean swim with their two dogs.

Gabriella left her wet brunette locks down over her shoulders as she headed for the car to fetch a towel to dry off.

Lifting her arms at one point, her impressive gym-honed six-pack abs were seen poking through. 

Meanwhile, Liam showed off his impressive rig by going shirtless for the swim.

He wore a pair of black board-shorts that appeared to be inspired by the aboriginal flag and artwork.

Liam and Gabriella were first spotted together in Byron Bay in mid-December 2019, during a lunch date with his parents, Craig and Leonie.  

The Hunger Games star, 31, went public with their romance in January 2020.

They were isolating together in Victoria at the start of the coronavirus pandemic, but Gabriella later joined the whole Hemsworth family in Byron Bay.

Liam has spent a lot of time in Byron Bay lately, following his split from ex-wife Miley Cyrus last year after just seven months of marriage. 

Gabriella seems to have been welcomed by the Hemsworths with open arms since then, and often attends family outings and celebrations. 

Miley was last linked to Australian singer Cody Simpson, but they announced their separation in August 2020.
