A resounding cheer erupted when on Monday three Palestinian teenagers shuffled on to the stage of a convention centre tucked away behind the golden beaches of Australia’s Sunshine Coast.

Two of their compatriots from war-ravaged Gaza could not make the journey to Australia and would instead attempt to compete remotely.
But this was a marked improvement from last year’s event in England, for which no Palestinian could secure a visa in time.
