A five-year-old girl allegedly abducted in central Queensland by a woman not known to the child has been found safe and well five hours later.

Queensland police issued an amber alert on Wednesday afternoon as they feared the girl taken from Malakoff Street at Biloela could havcev been in danger.

Police said a 24-year-old woman might have taken her between 2.45 and 3.15pm on Wednesday.

She was driving a blue 2004 Holden Commodore sedan with Queensland registration 035 XZQ and was possibly heading to the Emerald or Mt Morgan areas.

About one hour after the alert was issued, a member of the public alerted police after seeing the amber alert and noticing the vehicle in the Calliope area about 7pm.

The 24-year-old woman was currently assisting police with their investigations.

Police thanked the public for their assistance.
