Monique Cross, an Australian friend of Miss Ayliffe-Chung, said: "She was a gorgeous person. It's an awful tragedy - I can't believe it."

Other friends off Miss Ayliffe-Chung paid tribute on Facebook, with Tom Paenga writing: "R.I.P Mia. I know that I will not find someone like you again, so happy, so motivating, in good times and in bad times always you were drawing a smile...

"My condolences to your family and to those who had the pleasure of meeting you. Taken to soon but never forgotten!!!"
