Rudi Boa, from Culloden, near Inverness, was killed in New South Wales on Friday, 27 January.
Mr Boa was travelling with Gillian Brown, 29, from Inverness.
Alexander York, 31, from Essex, has been charged with his murder. He has appeared in court and was remanded in custody until March.
The couple had been travelling around South East Asia before arriving in Australia. They planned to go to New Zealand before heading home.
Miss Brown, who police said was "deeply traumatised" by events, said she and Mr Boa had been a couple since 2000.
"We were planning our round-the-world trip for a year beforehand and tragically all this was taken from us after four months," she said.
"We had planned to return to Scotland and settle down together.
"Rudi was more than a boyfriend. He was my best friend and we were deeply in love.
"I can't imagine my life without him."
The family of Mr Boa, an Edinburgh University graduate, also paid tribute to him.
"Rudi had a very laid back attitude to life, with a smile at all times," they said in a statement.
"He was popular and loved by all that knew him and made friends wherever he went.
"A much-loved son, brother, boyfriend who will be sadly missed."
Mr Boa graduated with a degree in chemistry from Edinburgh University before gaining another degree, in forensic science, from Napier University.
