New figures from a University of Sydney study show that almost 500 teens were hospitalised between 2012 to 2017 after playing at indoor trampoline centres.

While the most common injuries were sprains and fractures, nearly 20 percent of the study’s patients had serious spinal cord and head injuries, some causing permanent and lifelong disability.

The study's lead author, Dr Lisa Sharwood has called on the government to impose mandatory safety standards upon the booming trampoline centre industry, which currently operate without any such standards.
