Organisers say the night will be a “celebration of his life”, with DJs playing and friends paying tribute to the former Diamond Beach Club DJ.
Money raised from the night will go to Josh’s girlfriend, A, and their fourth-month-old son Christian.
Josh, originally from San Francisco in the US, was killed on February 28 after his motorbike was in a collision with a tour bus.
His mother Chery Hayes and younger sister Mia Medina arrived to Phuket early on Tuesday morning after they heard the news.
