He was acquitted of a further 13 charges.
Sentencing Keremete, Justice Palmer said Keremete was controlling and jealous towards women.
Out of his "appalling" list of 61 previous convictions, 31 were for violence involving women, Justice Palmer said.
He said a pre-sentencing report indicated Keremete posed a high risk of reoffending and needed to rationalise his actions. It mentioned evidence Keremete gave of considering himself to be a victim of a conspiracy by the victims and police.
"I accept you want to change but you will only do that if you accept what you have done," Justice Palmer told Keremete.
The judge said that on his release Keremete needed all the support his family could give him if he were to face up to the demons that drove his behaviour.
"Otherwise it will not stop the cycle of violence passing it down to the next generation, your children Mr Keremete."
He recapped trial evidence that Keremete had confronted one of his victims with a Samurai sword, threatening to cut her head off.
The other victim had told of the pain he caused her over a six to eight-hour period as being as if she'd given birth.
The charges Keremete was sentenced on were two of unlawful sexual connection, one of intentional injury, one of assaulting a female, one of threatening to kill, one of wounding with intent to cause grievous bodily harm and two of intentional damage, one of which he admitted during his trial.
