A man accused of slashing a Gold Coast woman's face with a sword had been on parole for less than a week when the alleged offence occurred.
Clint Darryl Hall, 35, was denied bail at Southport Magistrates Court on Wednesday.
Hall and stepbrother Thomas Ealam, 18, are accused of using martial arts-style swords in a dispute outside a Coombabah home on July 1.
The court heard Hall and Ealam had been confronted by the home's residents as they biked through bushland in the early hours of the morning.
After a physical altercation, the pair returned to their own home when Hall realised he had left some items at the other property including an iPad.
Police prosecutor Sergeant Bob Soper told the court when the pair returned to the Coombabah home armed with swords they were told the items had been taken by police.
Police then allege an enraged Hall struck Ingrid Brown, 35, on the face before slashing her partner Michael Liddell on the arm.
Sgt Soper told the court Ms Brown sustained "horrific injuries" which required emergency surgery, while Mr Liddell also had to have surgery on his injuries.
He said an account Hall gave police claiming he'd been struck by a shovel and had swung the sword in self-defence was "self-serving" and "doesn't add up".
The court heard Hall called emergency services upon returning to his home with Ealam, telling the operator he feared he had "hurt someone pretty bad".
Sgt Soper added Hall had been convicted of common assault just four weeks before the alleged incident and had been granted parole just four days before.
Magistrate Andrew Sinclair refused bail, saying Hall's parole status put him in a show cause situation, which he had failed to do.
"The offence is both very serious and resulted in substantial injuries," Mr Sinclair said.
