WHY would anyone want to go to Adelaide?

That's the question being asked by Victorian Opposition Leader Daniel Andrews who is disappointed the Duke and Duchess of Cambridge will visit the city of churches, but not Melbourne.

The royal couple will visit the northern Adelaide suburb of Elizabeth, which is named after the prince's grandmother on April 23.

Mr Andrews is shocked Melbourne has been snubbed and blames Premier Denis Napthine.

"How is it that we've got to a situation where the royals would rather visit Adelaide than come to Melbourne," he told reporters.

"What is going on in our state that we can't even attract members of the royal family, to come to Melbourne, to come to Victoria when they visit. Who would want to be going to Adelaide. Apparently the royal family do."

Prince William visited Victoria in 2010, touring areas devastated by the previous year's Black Saturday bushfires.

In 2011 the prince visited Victorian towns affected by floods.

Dr Napthine, who was visiting the fire and smoke weary Victorian town Morwell, said he would have loved for the royal family to come to Victoria and possibly boost the morale of Morwell residents, but he was not surprised.

"We in Victoria have been blessed with a number of royal visits, particularly from Prince William over in the last couple of years, Dr Napthine said.

"We'd love to have them and certainly invite them anytime in the future, particularly to visit Morwell."
