Dino Dibra (18 April 1975 – 14 October 2000), also known as The Sunshine Boy, was an Australian suspected murderer and a victim of the Melbourne gangland killings.

[citation needed] Police believe that Dibra and an old friend Rocco Arico, were partners in selling and distributing cocaine, ecstasy and amphetamines.

At the time, police had bugged Dibra's house and car, seeking information in relation to the Dome bouncer shooting.

[4] Whilst it had been believed that underworld figure "Mad" Richard Mladenich was also shot dead by Dino Dibra in a room in the seedy St Kilda Esquire Hotel on 16 May 2000, Mark Moran and Rocco Arico were also suspects, and on 30 October 2019 Victoria Police arrested Thomas “Little Thommy” Ivanovic for Mladenich’s murder.

He first appeared in episode four (Cocksure) and in his opening scene, Dibra was shown shooting a character named Bruno Bolotzi, who later died, outside a nightclub.
