Prime Minister Julia Gillard says the tragic death of a young man planking should serve as a warning to anyone attempting the internet craze.
Acton Beale, 20, plunged seven storeys to his death from an inner-city Brisbane apartment block in the early hours of Sunday morning.
Police said alcohol was involved, warning of the dangers of the fad where people are photographed lying face down in unusual public spaces. Ms Gillard described the incident as "really tragic".
"There's a difference between a harmless bit of fun done somewhere that's really safe and taking a risk with your life," she told reporters in Sydney.
"Everybody likes a bit of fun, but focus has to be on keeping yourself safe first."
