An artwork of 16,000 illuminated glass spheres designed as a touching Anzac tribute has pumped millions of dollars into regional Western Australia, according to independent research commissioned by Tourism Western Australia.

These visitors were responsible for a multimillion dollar cash boost to the region; with figures showing they spent more than $17 million during the six-month event.

The research also showed the event filled the rooms of accommodation providers in the region, with visitors travelling to see the artwork spending 82,238 nights in the South-West.

The art installation was exhibited at Albany's Avenue of Honour on Mount Clarence between Oct 2018 and Apr 2019 to commemorate the 100th anniversary of the end of the First World War and honour the Anzac legend.

The event smashed attendance expectations, attracting more than 186,000 attendees in total.

Field of Light: Avenue of Honour was supported by the State Government, through Tourism WA's Regional Events Program and Lotterywest.

The initiative was commissioned by independent non-profit cultural organisation FORM in partnership with the City of Albany.

Tourism Minister Paul Papalia commented, "The emotional pull of this amazing artwork has had a ripple effect that's benefited not only Albany, but the entire South-West region.

It was a stunning attraction in its own right and also complemented the National Anzac Centre in cementing Albany's reputation as Australia's point of pilgrimage for people wanting to experience the Anzac legend.

Its popularity has been phenomenal, bringing significant tourism dollars to the South-West economy and drawing visitors to the area's many attractions such as the breathtaking Stirling Range National Park, the natural beauty of the Valley of the Giants Tree Top Walk and the region's premium wines, to name just a few."
