A Brisbane university student accused of beating her Macedonian mother to death will remain behind bars.
Simona Zafirovska allegedly bashed Radica Zafirovska with a timber paling more than 20 times, with the 56-year-old's bloodied body found at her home at The Gap on October 28.
The 20-year-old was the one who called police, but suspicion quickly turned to her as there were no signs of forced entry or theft.
The Brisbane Supreme Court has heard that Zafirovska's suggestion that she'd been woken up by barking dogs also didn't match with neighbours' statements about noise at the time.
But her defence team on Tuesday submitted the young woman appeared "terrified" to first responders and could have been hiding under her doona in fear as someone entered and left her room.
Zafirovska did not appear in the Brisbane Supreme Court when her bail application was refused on Tuesday, with the judge ruling she was a potential flight risk.
