Sydney Harbour is preparing to put on its best for the Pope's visit in July.
It will provide the backdrop for Pope Benedict XVI to make his way to Darling Harbour by boat.
World Youth Day co-ordinator Bishop Anthony Fisher says he's expected to be greeted by a massive crowd.
“The young people with flags representing all the nations of the world will gather with him on his way into Sydney Cove.
“Thousands more will join the Captain Cook flotilla that follows and hundreds of thousands of young people will await him as he alights this ship for the welcome ceremony.”
