The sister of a soldier who died in the firebombing of Brisbane's Whiskey Au Go Go nightclub says her birthday has been bittersweet since the attack almost half a century ago.
Leslie Palethorpe was one of 15 people who died from carbon monoxide poisoning after two drums of fuel were thrown into the downstairs foyer of the Fortitude Valley nightclub and set alight about 2am on March 8, 1973.
The following day was his sister Helen's 14th birthday.
