Asked if the ship could sink, Mr Palmer told reporters: "Of course it will sink if you put a hole in it."
He added: "It is going to be designed so it won't sink.
"It will be designed as a modern ship with all the technology to ensure that doesn't happen.
"But of course if you are superstitious like you are, you never know what could happen."
Mr Palmer said design work in conjunction with a historical research team had commenced on the new Titanic.
It would have the same dimensions as its predecessor, with 840 rooms and nine decks.
Mr Palmer has established a new shipping company, Blue Star Line Pty Ltd, which has commissioned CSC Jinling Shipyard to build and co-ordinate the construction of Titanic II in China.
The Chinese navy has been invited to escort Titanic II on its maiden voyage to New York.
