Man went into 'survival mode' as he and girlfriend shot

A man who was shot five times outside a Queensland home has denied destroying its security cameras and planning to attack the resident with a knuckleduster.

Brendyn Wade Clark has pleaded guilty to causing grievous bodily harm to Adrian Steven William Hing and wounding his girlfriend Clarice Laura Warren by shooting them with a .22 calibre rifle on June 22, 2019 in the south Brisbane suburb of Sunnybank Hills.

Prosecutors rejected the grievous bodily harm plea and took the case to trial, urging the jury to find Clark guilty of attempting to murder Mr Hing.

On the second day of the trial in Brisbane Supreme Court on Thursday, Mr Hing testified about going into "survival mode" after realising Clark, while standing on the front verandah of his home, had shot him in the stomach.

Mr Hing said he had been sent an "onslaught of aggressive messages" from Clark as well as a woman who blamed Ms Warren for interfering in her relationship with Mr Hing.

The dispute resulted in the woman taking Mr Hing's $6000 mountain bike and Clark cutting its carbon fibre frame in half.

Mr Hing testified that he wanted "to get the person who cut my bike" and went to Clark's home at 7am with Ms Warren and his pit bull Archer to find the name of the perpetrator.

"I saw Brendyn come out onto the verandah, he stopped, pointed the weapon and fired. I heard the shot," Mr Hing said.

"I turned to Clarice and told her to run. She replied 'I can't, I've been shot'."

Mr Hing said he was shot in the stomach as he and Ms Warren retreated to a nearby bus stop shelter as Clark walked down his front stairs towards them.

Mr Hing said he was shot twice while holding up his hands in a defensive posture and he decided to charge Clark after he shot Ms Warren in the leg.

"I tried to throw a punch but did not realise I was shot in the shoulder and the bone was broken," Mr Hing said.

"I was trying to hold onto him but my finger had been shot off and I lost my grip."

Mr Hing said Clark aimed the gun at his head but was stopped by a bite from Archer, who had returned to the scene after being scared off by gunfire.

Under cross-examination from Clark's barrister Bernard Reilly, Mr Hing said he was unaware Ms Warren had brought along a knife and baton in her backpack but he did bring Archer to aid in any physical confrontation.

"When you went to my client's house on June 22 you were still angry with him as you were told he cut your bike?" Mr Reilly asked Mr Hing.

"No, I was told it was someone else. Brendyn had been friendly on the phone," Mr Hing replied.

Mr Hing maintained under cross-examination that Clark deliberately aimed a firearm at his head.
