The display is the first of a series that TPA would like to install in the Kokoda Track region. It has been developed as part of the Heritage Supporting Tourism project.
This new interpretive display will provide visitors with an insight in the shared history between the two countries, as well as the region's natural, cultural and military history.
Tourism Minister Tobias Kulang unveiled the interpretive display on behalf of the Kokoda Initiative and said this is a significant achievement in preserving this tourism heritage and site.
Kulang said the Kokoda Track is an important landscape to both PNG and Australia and will remain a major landmark for both countries.
He said it is important that the locals understand the importance of this interpretive display so it can remain for the future generation and for tourists to see and educate themselves about the track.
The event was attended by both representatives of the PNG and Australian Governments.
