"The Queensland Rugby League is deeply saddened to learn of the passing of talented Redcliffe Dolphins player Liam Hampson in Barcelona," the league said in a statement, citing Liam's father Brett as "sadly confirming his passing".
Although Catalonia's regional police would not disclose the name of the victim, it said that a 24-year-old Australian man who had been reported missing on social media was found dead at 3 p.m. on Wednesday at Barcelona's Apolo concert hall and nightclub.
Police were treating it as an accidental death caused by a 10-metre (32 feet) fall into an inner courtyard, a police spokesperson said.
Hampson was on a trip across Europe with fellow rugby players, pictures posted on their Instagram accounts show.
"We are devastated to find out Liam had an accident and did not survive. We are so heartbroken," his sister Tiarna wrote in an Instagram tribute, calling him the best brother she could have ever asked for.
She thanked his travel companions for helping with the search and making sure "his last days were the best of his life".
An autopsy was conducted on Hampson on Thursday, a spokesperson for Catalonia's Justice department said, declining to disclose its results due to privacy reasons. The autopsy report will be available to a local judge assigned to the case and to Hampson's family.
A spokesperson for Catalonia's court system said she did not have specific details on Hampson's case.
The Apolo and the Australian consulate in Barcelona declined to comment. Australia's Department of Foreign Affairs did not immediately respond to a request for comment.
