Police Association secretary Wayne Gatt said the incident highlighted how a shortage of resources in the Macedon Ranges Police Service area was increasingly putting police and the public in danger.

Police said a body was discovered at a house on Rodney Street in Gisborne about 6.30pm on Sunday.

Mr Gatt said the suspect, 55, had to press an intercom button which took him through to Kyneton Police more than 30 kilometres away.

Kyneton police established there was an officer inside the locked Gisborne station, but Mr Gatt said their presence was a lucky coincidence. He was rostered to be on patrol that afternoon and was only at the station to finish another task.

It also meant the officer had to approach the man by himself, a situation Mr Gatt said was unacceptable.

Mr Gatt said pressure had increased in the region since Woodend station closed two years ago and was compounded by the fact that the Macedon Ranges station was expected to be closed for another six months.

"The reality is the community is suffering from this lack of resources - which are already at breaking point," he said.

"We are now also seeing our members placed at risk because of this and we simply cannot allow it to continue.

"Victoria Police needs to act quickly and provide an urgent injection of resources to the Macedon Ranges PSA to enable them to do their jobs safely and support the community."

He said it was only recently that Gisborne station began closing at night because there were too few police to man it.

Victoria Police broadly confirmed the report, but would not comment on Mr Gatt's claims about resources or the repeated warnings from the association.

Meanwhile, neighbours are in shock that the normally "very quiet" Gisborne street is now buzzing with homicide detectives.

For one Rodney Street resident, Dale Takle, an untouched pile of newspapers and junk mail was the only indication something wasn't quite right two doors down.

He presumed the owner of the letterbox might have been on holidays, but knew it was far more serious when detectives turned up at his door.

"I didn't see anything, didn't hear anything, didn't know anything until the police knocked on the door (Sunday) night," Mr Takle said.

"I'd been home all week and didn't hear any disturbances. There was nothing suspicious or untoward except the number four letterbox was overflowing. I was actually thinking on bin night I should clean it up for them."

Mr Takle said detectives told him the man probably died some time between Thursday last week and Sunday.
