Mississippi - London to Australia

I'm trying to find some information on a ship called the Mississippi which arrived in Australia March 7th, 1854 from London. It has been described in newspapers of the time as a Norwegian ship. Here is one of the descriptions I've found of it: "Mississippi, barque, from London. 31 passengers" I believe my great-great grandfather was onboard, so any information you could provide would be much appreciated esp crew lists.
