You may be accustomed to telling Siri what to do, but what about taking her advice... and taking a holiday?

At least the advice of the Australian voice of Siri, Queenslander Karen Jacobsen.

Apparently a campaign with Wavemaker and broadcaster SCA to promote tourism in the Whitsundays region has already scored $500,000 of sales.

Mumbrella reports SCA Brisbane's Tony Byrne that use of the authoritative voice "brought a level of believability to all the airtime".

A staggered campaign rollout follows restrictions in different states, and will include TV, digital displays, OOH, content partnerships and social. So far enquiries have led to 13,700 travel quotes and more than 430 bookings.
