An intervention order is similar to an apprehended violence order (AVO).
Rhyce was accused of assaulting Vanessa in April.
Sierra took to Instagram to share a photo of herself with what appears to be a black eye.
"7 days of isolation and I’m back to myself again. Those closest to me already know what happened. This was taken the day I left and it does not even hint the extent of what I went through."
Vanessa continued: "Domestic violence isn’t a f****ing joke, so here is (literally) a taste of your own medicine. On a completely separate note, @rhyce_power how is Thailand?"
Rhyce addressed her claims with a statement released via his legal team.
The statement reads: "Our client Rhyce Power has been notified by media that an allegation has been made against him. He is yet to be provided with those exact details but is now aware that a smear campaign has commenced from an ex-partner which is obviously very disappointing given their continued friendship since the relationship ending."
The statement continued: "He is determined to defend himself and will return home from Thailand immediately to do so. Rhyce will have no comment at this stage."
