Almost four years before it’s believed she was murdered at the hands of her father, Katrina Miles penned a haunting poem about domestic violence.

The 35-year-old Western Australian mum, along with her four children Taye, 13, Rylan, 12, Ayre, 10, and Kayden, eight, were shot dead in their beds on Friday morning. It’s suspected Peter Miles, 61, was the gunman, who then shot his wife Cynda before turning the gun on himself at their Margaret River property in an act of family violence.

The resurfaced poem, titled ‘I am battered not broken’, was first released by domestic violence campaign group Red Heart and shared on Facebook by Cynda in October 2014.

It speaks of "open handed fists" and verbal abuse with phrases typical of a violent partner, such as "No one would want you", "worthless" and "bitch".

"The shrieks of my children, the echo of my shouts, the thump of my dignity slammed against a wall, the odour of stale beer has a name called fear," one part reads.

It's not clear whether the poem is fictional or based on Katrina's lived experiences. However, in it the narrator asks "how can I be five places at once?" and references "my only daughter" and "three sons".

"I look in the young eyes that still love me. I ask myself, so ashamed, 'How can my children still love me?' I stayed so long, so long."

In a statement to media, Katrina's ex-partner and the father of their children, Aaron Cockman, said that he had been "cut off" from his kids for six months and blamed Peter and Cynda Miles for that.

I’m battered not broken

By Katrina Miles

I stare into the depths of my worries The crease between the frown The hollowness of my cheeks is an echo My stomach beats to the litany of my hurts

I stare and stare and stare Hoping for salvation Hoping hoping hoping All peace is lost, fragmented, worn I glare myself into submission

The shrieks of my children The echo of my shouts The thump of my dignity slammed against a wall The odour of stale beer has a name called fear

The creak of a door The sound of a petrol ute Stiffens our shoulders, hurtles our spines uptight Paste those fake smiles, quick hurry quick hurry quick hurry

Shh shh child Please Please Please be good Be calm, be still Make it easy,

Oh the shame Make it easy How can I be five places at once How can I save my family from open handed fists, from cruel, persistent words

Obey, Obey, Obey, Obey How I hate that world, that word Obey Obey Obey obey How can I break free

There is no freedom for me I stare, I stare, I stare I fear I am lost. But my children my children my children

My children, my children, my children They are not lost They are not lost! And so nor am me

I shout, I shout, I shout No No No No I leave, I come, I leave, I come I have left ....

In my head I am there Here I am suspended Save my children, save, save, save them In my head I am there

The walls echo with the thump of my body The fists in the doors The creak of a beer bottle being opened The shame behind our doors.

I look in the young eyes that still love me I ask myself, so ashamed How can my children still love me I stayed so long, so long

I am battered My cells echo with his words 'No one would want you', 'worthless', 'nutcase', 'problem', 'your the problem', 'your fault', 'bad mother', 'look at your family history', 'I love you', 'bitch' ..... The agony is a death to my soul, pin pricks in my skin

I asked God to save me and he was there I asked myself to save me and yet I could not I look into my only daughter's eyes, I look into my three son's and I can

I am battered, I am not broken I am strong, I am fragile I am bruised so deep I ache I ache I ache I ache

I am battered, I am not broken
