The Queensland government is urging Google to fix its Maps application over claims inflated travel times are deterring tourists to the outback.

Acting premier Cameron Dick says he intends to send a letter to the head of Google Australia and New Zealand to fast-track amendments of the travel times, which outback businesses say add up to six hours to journeys.

Outback Queensland Tourism Association Manager Peter Homan says tourism is crucial for the outback towns facing drought, hence this issue must be addressed immediately.
