A man known as Melbourne's 'Tinder rapist' has told a court he has finally realised the extent of damage he inflicted on victims, ahead of his court sentencing.

But the women who fell prey to Glenn Hartland have dismissed his remorse as the kind of "lies and deceit" with which they are only too familiar.

Hartland, 44, watched from the back of the room of his pre-sentence plea hearing in the County Court today as three victims detailed how the attacks devastated their lives.

The brother of a fourth woman, who took her own life earlier this year, spoke of the "permanent and unforgivable" damage inflicted upon her family.

Prosecutor Andrew McKenry described in grisly detail the attacks in Melbourne's eastern suburbs between May 2014 and March 2016 over which Hartland has pleaded guilty to three charges of rape and one of indecent assault.

His surviving victims quietly wept and one had to leave the room as their statements were read aloud.

Hartland seduced the women via dating app Tinder and entered intimate relations with them before engaging in forced, non-consensual sex or indecent assault.

The rapes occurred in the victims' homes, with Hartland screaming and abusing one from outside until she let him in.

The indecent assault was committed in a toilet of a St Kilda hotel where Hartland pinned the victim against the wall of a cubicle and ripped off her underwear.

One woman spoke of how Hartland would combine "grandiose romantic gestures" and charm with threats of suicide and violent mood swings to control and manipulate his victims.

All three described themselves as intelligent and strong-willed women prior to the assaults. But Hartland had left them riddled with self-doubt and post traumatic stress disorder and derailed their personal and professional lives.

He also faces charges of use of carriage service to harass and distribution of intimate images.

Judge Paul Higham described the latter as "revenge porn" and particularly serious, as the explicit videos and photos "could never be reclaimed".

Late on, Hartland's barrister Greg Barns said he spoke with his client briefly after hearing the prosecution's case.

"The penny has finally dropped," Mr Barns said.

"He's appalled by what he's done."

Mr Barnes said his client had accepted he would "go to jail for a lengthy period of time" and be a registered sex offender for life.

He noted his client's troubled childhood as well as a substance abuse and mental health issues.

Hartland was born in New Zealand and became a ward of the state by the age of 12 months.

After numerous breakdowns with foster families and failed attempts to be reunited with his mother he moved to Western Australia to be with her in 1981.

Judge Higham accepted Hartland's guilty plea had reduced the impacts of a trial on the victims, despite Hartland's previous attempt to change that plea.

Speaking outside court after the hearing, two of Hartland's victims described his lawyer's comments as "disingenuous".

"I've heard it all before," said one.

"It's his 'I'm a victim, poor me' routine."

Hartland will be sentenced on May 10.
