A gaming addict who allegedly bashed his pregnant girlfriend during a Fortnite binge was himself the victim of domestic violence.

Luke James Munday, 26, was last week charged with common assault after his livestream allegedly showed him attacking Grace Campbell, 21.

But this was just the latest in a series of violent incidents and accusations that were common over the couple's 'toxic' five year relationship.

Last year, Campbell was given a 12-month good behaviour bond for repeatedly hitting him during a blazing argument about money.

But a year earlier, Campbell was given a 12-month good behaviour bond for repeatedly hitting Munday during a blazing argument about money (injuries pictured)

Shocking photos obtained by Daily Mail Australia showed the injuries Munday suffered during the attack on September 8, 2017.

He was seen with hand prints on his chest, red marks on his neck and torso, and a swollen lip from where he was repeatedly struck.

Munday was also kicked in the leg and hit multiple times on his back by the 'hysterical' Campbell, court documents revealed.

The argument started in the kitchen of their $530-a-week rental home in Oran Park, western Sydney, over how little money the young couple had.

Munday was an IT worker supporting her and their two toddler girls with Campbell contributing $650 a week in welfare payments.

The fight started in the kitchen before Munday left to get changed in his room, but Campbell followed intent on continuing.

She then suddenly kicked him in the upper left leg and used her right hand to slap him in the upper left chest.

Munday defended himself by grabbing her around the shoulders and placing her on the ground, the statement of facts read.

After arguing some more, Campbell left and called her parents to falsely tell them Munday had assaulted her.

Munday called out to demand she stop lying, and she responded by throwing a broom and a baby gate down the hall towards his room.

She then took porcelain bowls and other crockery from the kitchen and threw them into the hallway, breaking them and leaving holes in the walls.

Munday returned and Campbell hit him several more times before he grabbed her by the shoulders and pushed her back.

The sad saga ended with Luke James Munday, 26, being charged with domestic common assault and banned from his family home - unable to see his children

Campbell told Daily Mail Australia her partner would binge-play the game at his desk (pictured) for eight hours at a time

Campbell then grabbed a fruit bowl from the drying rack and threw it, then the rack itself, at him but he deflected it away and said he was calling police.

The enraged mother hit him repeatedly and knocked over a bin while he looked for the police station's number.

'Don't hit me,' police heard Munday say, along with there being 'a female hysterical in the background'.

Campbell swatted the phone out of his hand and took off with their youngest daughter, aged just six months at the time, who watched the fight.

Police arrested Campbell the next day and served her with a restraining order on Munday's behalf. She had just a minor scratch on her shoulder.

'During the interview she was initially very vague, stating that she recalled throwing water on [Munday] sparking the physical altercation,' police said.

When pressed for details she said she couldn't remember because it all 'happened so quickly'.

A magistrate convicted her of domestic common assault and gave her a 12-month good behaviour bond.

However, this wasn't the couple's first run-in with the law. In 2015, Munday was served with an AVO after Campbell injured her hand and elbow.

On September 20, 2015, the couple were on the rocks and fighting about custody of their newborn first daughter.

Campbell claimed she was leaning against Munday's Hyundai Excel, which had a sticker of two stick figures having sex on its rear window, when he assaulted her, according to separate court documents.

'We were yelling and screaming at each other, then he pushed me, my elbow went through the glass,' she told police in an interview.

'I slapped him across the face for pushing me so hard, then he grabbed me by the shoulders.

'I just froze, I didn't feel pain. I pulled glass out of my hands and that's when the pain started.'

Campbell claimed the argument started the night before when Munday was at the notorious Defqon1 dance music festival all day.

She broke their baby's pram when out shopping and called him to come pick her up, but he refused and called her a 'f**kwit'.

His brother Daniel Munday (pictured) said the couple had been locked in a cycle of 'tit-for-tat' conflict for most of their five-year relationship

He eventually left at 11pm and picked her up from her cousin's place at 1am. They argued through the morning about him earlier promising to spend the day with her, but then just wanting to sleep.

She claimed he over the previous months told her he would take the baby from her as she was an 'unfit mother'.

'I'm going to take her, I'll get custody and you'll never see her again,' he allegedly said. Campbell also claimed he often said 'I'll punch you' during fights.

Munday's brother said the argument that landed him in a jail cell was no different to dozens of others, except that it allegedly escalated into violence and was livestreamed around the world

Campbell also claimed Munday pressured her to have sex two weeks after she gave birth despite her wanting to wait at least a month.

'He would guilt trip me for days to do it and I would give in, not enjoying it,' she alleged to police, saying she had stitches from giving birth.

She claimed he said: 'I don't see what the problem is, the stitches aren't inside you so why can't we just do it?'

Munday instead claimed after he walked outside to end the argument about custody, Campbell walked outside and without saying a word, punched the car window and smashed it.

'Grace stood there in shock looking down at her hand like she was surprised that she had put her hand through the window,' he told police.

He said he then grabbed her shoulders and was slapped, then said he was calling the police.

Munday told officers that was the first time he put his hands on his girlfriend, and it was only in defence. 'I have never hit her,' he said.

Munday said Campbell's parents came to the house and threatened him, then started to clean up the glass until police stopped them.

Munday, 26, appeared at Camden Local Court in Sydney last Thursday morning

Police initially arrested Campbell for malicious damage but changed their minds after hearing her story and slapped Munday with an AVO.

They said her injuries - scratches on her elbow and hand but no forearm cuts or swollen or injured knuckles - were 'not consistent with striking the window' as Munday claimed.

However, they couldn't press charges against either party because 'both versions [of events] hold credibility'.

Campbell formally cancelled the AVO in July 2016 and the pair continued to live together, with some interruptions, until last week.

Munday's brother Daniel Munday, 24, said such incidents were the lowest points in the cycle of conflict they had been locked in since they began dating five years ago.

'They have a toxic relationship with so many domestics it's hard to keep track of them,' he told Daily Mail Australia.

'Their arguments can be brutal and Luke has moved back to our grandparents' house numerous times afterwards.

'After a few weeks the dust settles, they patch things up and he goes back to live with her, they're good for a little bit, and then it happens again.'

Daniel Munday said neither were blameless and both needed counselling.

'I'm not siding with Luke or excusing his actions, I don't even really like him, but the real victims are their kids,' he said.

'He's recently been snapping back at her harder and she knew he was close to breaking point.

'They both need help but refuse to get it and I've been worried it could escalate into something really bad.'

Daniel Munday said his brother refused to break up with Campbell because he didn't want his children to suffer the same childhood as him.

Munday 'never knew his father' and his beloved mother Suzanne Munday died about when he was just 12 years old.

Munday was raised by his grandparents and his brother spent time in the foster care system, Daniel Munday said.

'He's worried that if he leaves her she will get custody of the kids and he'll be lucky to ever see them. He doesn't want them to have the childhood we did,' he said.

Daniel Munday said when the couple first got together, when Campbell was just 16, his brother was an unemployed layabout who played games from morning until late at night.

'When Grace told him he was pregnant with their first child he pulled his finger out and went to TAFE and eventually got a job,' he said.

'Gaming has always been an escape from how we grew up for him and recently he's gotten addicted to it again.'

Campbell said as Munday's addiction to the popular game worsened, he increasingly shunned his family to spend more time online with strangers.

'Some days he would finish work, play Fortnite until he fell asleep in his chair, then get up and do it all again,' she told Daily Mail Australia.

Campbell said it wasn't always like this, describing how the mop-haired IT nerd turned into an 'angry person' who would play all night.

'He got famous and started playing six to eight hours a day for his fans,' she said.

'As he got more addicted he changed, he became an angry person.

'He wasn't spending enough time with the kids and it was a struggle every day to get him to leave the computer for anything.'

Munday's brother said the argument that landed him in a jail cell was no different to dozens of others, except that it allegedly escalated into violence and was livestreamed around the world.

Campbell appeared to throw a cardboard box and other objects at Munday as she demanded he stop playing, before he got up and confronted her.

He then allegedly slapped her in front of their children as Campbell screamed and then called him a 'woman basher'.

'I hope all of you people know that I'm pregnant and he just bashed me,' she said.

The couple continued their screaming match and Munday seconds later could be heard telling her to 'f**k off... leave me alone for 10 f**king minutes'.

Munday faced Camden Local Court last Thursday where his assault charge and an AVO were adjourned until January 10.
