QUEENSLAND'S Attorney-General is appealing a suspended sentence given to a teenage P-plater who killed a pedestrian while looking at her mobile phone.

Meghan Catherine Elizabeth Hopper, 19, killed Taiwanese fruit-picker Chen-Chuan Yang, 25, while looking at Google Maps as she was driving on July 7, 2012.

A second pedestrian, Kwan-Jun Wu, 30, was severely injured in the incident at Elimbah, north of Brisbane.

Hopper was 17 at the time of the fatal crash.

Five months after the death, she was fined for again looking at Google Maps on her phone while driving.

In the Brisbane District Court on Monday, Hopper was handed a 30-month suspended sentence over the crash.

Attorney-General Jarrod Bleijie on Friday said he had ordered the Director of Public Prosecutions to lodge an appeal against the sentence, on the grounds it was manifestly inadequate.
