Elsewhere, friends have remembered Ofner - a stuntman and actor who was due to feature in Channel 9 reality TV series Australian Ninja Warrior later this year - as an adventurous, hard working young man who loved his daughter and had an immense lust for life.
Lovingly referred to as 'Yogi', hundreds of friends paid tribute to the carpenter turned stunt actor.
Stunt actor Philippe Deseck said Ofner had an "endless supply of love for his little girl and family".
"We will miss you and know that your little girl will always shine bright just like you did," Deseck wrote.
One friend posted a moving eight-minute video of photos of Ofner, surrounded by his family and friends.
Police have not commented on the weapon or ammunition involved, but their investigation will focus on whether workplace health and safety laws were followed.
Just a few hours before he died, Ofner uploaded a video to Instagram of props - including two guns and stacks of cash - being used for the film clip and made an apparently light-hearted reference to "faulty props".
The ABC has reported Ofner was shot at close range with a gun using blanks, a type of cartridge that has no bullet but contains gunpowder that are still dangerous when fired.
Australia's film and television union, the Media, Entertainment and Arts Alliance, says the death will spark a review of the film safety code, which is not legally binding but sits alongside enforceable workplace health and safety laws.
