The co-stars were joined by fellow cast members Sam Frost and Jake Ryan.
At one point Ada – who plays the character Leah Patterson-Baker on the hit Channel 7 show – showed off her slim physique in a maroon bikini worn beneath a floral orange sundress.
It appeared from the snaps she had recently been for a dip in the sea as her long brunette hair appeared tousled.
Separate snaps showed fan favourite James Stewart – who plays Justin Morgan – returning from a surf.
In the photos, James sported blue and black board shorts and a bare chest, while carrying a surfboard in one hand.
At one point co-stars James and Ada were joined by a pal as they sipped what appeared to be coffee from take away cups.
