Peter wasn't happy about the other guy saying there wasn't a God," Ms Campbell said.
Mr Lau said: "The other guy was cursing God and the Bible.
"Peter was defending God and saying that he was our creator."
Ms Campbell said the accused said, "You better apologise to our Lord or I'll f---ing kill you."
Mr Lau and Ms Campbell went inside the property and Ms Campbell said she saw Mr Rattya run to his bedroom, grab a bow and arrow and run outside again.
The court was told she watched Mr Rattya aim the bow at Mr Alihromic.
Ms Campbell said Mr Rattya giggled and laughed after he allegedly shot the other man.
So I gather we can expect bow confiscation from down under any day now...
