Gordon was stabbed to death early on Saturday morning after chasing a group of intruders from his Doncaster home.

His body was discovered less than a kilometre away.

While he pursued the thieves, his partner was on the phone to police.

"Honestly, scum - scum of the earth," Natalie said of his killers.

"How any decent person could do that to another human being is beyond me."

The GP grew up in Gippsland and had a charisma about him that everyone around him loved, his sister said.

He moved to Melbourne around 10 years ago to pursue his passion of medicine and helping people.

But just as he started hitting career highs, Gordon's life was cut short.

There are growing floral tributes at the scene of his death.

His colleagues at the Box Hill Superclinic have also opened up on the loss

"Dr Gordon was well-loved and respected by everyone and our prayers and thoughts are with his family and loved ones," the clinic said in a statement.
