The use of the lighthouse has been approved for two years, with a review due before approval for an additional two years is granted.

The plastic transfer vinyl logo is 1.5-metres high and two metres wide.

President of the Kiama-Jamberoo RSL Sub-Branch, Ian Pullar, and Kiama councillor Dennis Seage (who is also secretary of the sub-branch) played an integral in having the vision come to fruition.

Mr Pullar said the logo and lighthouse were an ideal match.

"The people refer to the lighthouse as an icon, and the Anzac 100-year logo is an icon. You're matching one icon with another."

Mr Pullar said there was Anzac relevance to the Kiama Lighthouse.

He said the first Anzac Day remembrance service in Kiama, in 1916, was conducted at the showground, adjacent to the lighthouse.

During war time, lighthouses served vital navigational functions.

"All major troop movements in World War I were by sea," Mr Pullar said. "Lighthouses were, for many soldiers, the last sight they ever had of their homeland.

"Soldiers who trained here would have gone past Kiama in their ships, and lighthouses were so important.

"The ships and people on there would have been guided by the lighthouses as they went overseas.

"The lighthouse at Kiama was mentioned in a poem written by a Private J.W. Carr while under training at the showgrounds," Mr Pullar said.

"He was killed in action at Villers Bretonneux."

Mr Pullar said the logo's placement at a tourism drawcard like the blowhole would also help educate about the Anzacs.

"An awful lot of people will see that and if they don't know, they'll ask, 'what's that?"'

Mr Pullar said the logo would be a highlight of the lighthouse Dawn Service from 5am.
