An urgent search is underway in Brisbane for a teenage woman and an eight-month-old boy, who police say may be at significant risk.
The young woman and baby, who are known to each other, left an address on Logan Road at Holland Park on Brisbane's southside around 10:35am on Thursday
Police said they did not make a scheduled appointment soon after, and normal lines of inquiry have now been exhausted, leading to authorities issuing an Amber Alert on Friday afternoon.
Police said they had concerns for the boy's safety.
He's described as Aboriginal in appearance, wearing a blue and green striped Bonds singlet and denim jeans.
The 19-year-old woman is also Aboriginal in appearance, 160cm tall with a proportional build, and last seen wearing a black and white striped dress.
