About half an hour before she died, Nayler sent her mother Vivien Nayler a text.
"Have arrived safely in Melbourne," she wrote.
She added she was about to leave a nightclub in the city and head back to her friend's home, the Age reported.
Nayler ended the message as she always did: "Love you."
Vivien Nayler said she wanted to be clear that initial media reports that said her daughter was playing Pokemon Go were not correct.
"She wanted to see her friend and came down to meet him on Friday," Vivien Nayler said.
The friends were almost home after a night out at a nightclub in the city when she was killed.
"It has been dreadful, we can't believe it," Nayler said.
"Her father and I are devastated by this tragedy."
She said her daughter had always told her she was her best friend.
"I know all mums say this but we really were so close, and that's why she texted me that night, we were always in contact with each other, always so close."
Nayler and her husband Nabob (known as Don) have travelled to Melbourne and plan to take their daughter back to Noosa for the funeral when the Coroner releases her body.
Housemate and friend Sarah Staltare said Tanami had an "infectious energy" that often lifted people's spirits, the Age reported. "There are certain people that you are drawn to, people who are infectious and make your heart warm. Tani was one of those people," she said.
"I'm so heartbroken that our time has been cut short but her impact on my life and those around her will live on forever. Tani is the most beautiful and caring soul and wherever she chooses to be now I know that that place will be full of light, new adventures, love and not to mention amazing style.
"She would have already made so many new friends in heaven."
Tributes for the bright and bubbly friend were also flowing on social media.
"So sad to hear the news that this amazing girl is no longer with us, from school days, crashing on her couch after big nights in Noosa and building a whole house worth of flat packs with her this girl was never short of a smile or positivity," one friend wrote.
"Truly genuine people like this don't come around much anymore. Tanami Nayler you truly were one of a kind."
"So sorry beautiful girl," another friend wrote.
