It was an average Thursday night as Christian's three children got ready for bed upstairs and his wife prepared food in their Caroline Spring's kitchen for the following day.

He got up from the television at about 10.40pm to investigate after his wife heard a loud noise that sounded as though someone was trying to open the door to their Barn Elms Parade home.

He soon realised the door had been kicked in.

"I couldn't believe what I was seeing - there was a man with a steel pole to my left and to the right there was another guy holding something I couldn't see," Christian told reporters on Friday.

The men told him to get on the floor, as his wife hid behind the kitchen bench.

From the floor, he threw household items at the men, including a fruit bowl, and screamed at them to leave.

"One guy said, 'shoot, him, shoot him' and then I heard a pop and I saw a bit of a spark," Christian said.

The single bullet missed him, ripping a hole in wall behind him close to where his wife was hiding.

Christian continued screaming and throwing items at the men until they retreated.

They fled through the front door and were last seen running east on Barn Elms Parade towards Caroline Springs Boulevard.

Christian checked on his wife and kids, who were in tears after hearing the commotion.

"They thought that I got injured because that heard the gun," he said.

"It's like surreal. It's like what's going on here, I'm in my own home and these guys are intruding and they have got weapons and they're firing at me.

"It's pretty scary to be honest."

Detective Inspector Steve Clark implored anyone with information or CCTV footage to come forward.

"It's particularly traumatic to have your home broken into and be menaced with weapons," he said.

Inspector Clark said a small hatchback seen nearby minutes before the intrusion could be connected.

The man with the metal bar is described as about 170cm tall, with a slim build.

The man with the firearm is also described as about 170cm tall, with a medium to solid build and a big head and a broad face.

The first man is thought to have been speaking with a Middle Eastern accent, while the second an Islander or New Zealand one.

Both men were wearing dark clothing and a black mask covering their faces.
