Shaun Kenny-Dowall's father John Dowall says his son is "1000 per cent" innocent of the domestic violence allegations levelled against him.
Kenny-Dowall was arrested on Saturday and charged with a string of offences including the common assault of, and stalking of his former partner Jessica Peris.
The Kiwi international willface Waverley Local Court on Thursday, where he is expected to plead not guilty to all 10 charges.
Dowall, a Paralympic gold medallist, has taken to Facebook to protest his son's innocence.
"He is 1000 % innocent of all the charges that have been put before him i repeat 1000% innocent and i will stand by him every step of the way for ever long it takes until his name character and integrity has been restored," John wrote in a post late on Monday night next to a photo of he and Shaun.
"No stone will not be turned over in defending him and the allegations that he has wrongly been accused of, I cant begin to tell you all how determined i am to see justice served here and his and my familys integrity restored.
"Im extremly confident that one day shaun will be able to have his day in a court of law and begin to restore what should never been taken away from him his pride his spirit and his integrity."
Kenny-Dowall didn't play in the Sydney Roosters' win over the Warriors last Sunday amid concerns over his welfare and he hasn't been named to play in the tricolours' round-20 NRL fixture on Friday night against the Wests Tigers.
"The allegations labelled against my son have devastated him his family and all our friends," Dowall continued.
"But ill let you all know it hasnt devastated me or my spirit thats because i love my son through the good times and the bad times an unconditional love based on honesty integrity character and just being the beautiful man that we all know love and trust.
