A site which played a pivotal role in World War II communications now belongs to Redland City Council, and they want local people to help decide what to do with it.
Negotiations with the federal government began in 2015 to buy the former US radio receiving station site at Birkdale.
It received Australia's first radio message when Japan surrendered to the Allies in 1945, which was then relayed to Douglas Macarthur's Pacific headquarters in Brisbane.
There are unconfirmed stories that General Macarthur slept on the site, he was that fearful of the enemy severing communications.
"Not only is it a significant part of Redlands history, it's a significant part of world history," Mayor Karen Williams said.
"For a significant message like that to have passed across here, it's something you can never take away from the Redlands.
"For me, to be able to put in a little flag at Capalaba, it really makes me proud."
Almost three-quarters of the 62 hectare site will be conserved under the city plan. The remaining 17 hectares are zoned for community purpose.
Not only does it add to the history of the city, it adds to the environment too," Ms Williams said.
Ms Williams said it was an opportunity to secure the site's legacy.
"Council's commitment today is to ensure that the future of the land is part of well-informed conversation with the Redlands Coast community."
Bowman MP Andrew Laming called it the longest real estate deal in history.
"It took 5270 days and dozens of ministers. It's the longest real estate deal in history," he said.
"The greatest victory being a sale to Redland City Council, rather than into private hands, which the law would usually require.
"There isn't a deal like this anywhere, nationwide."
