Royalists have hailed Prince William's engagement as a move that will breathe fresh life into the royal family and give it new relevance in Britain and Australia.
Katie Dunkley, president of the WA Victoria League for Commonwealth Friendship, said the engagement was fantastic news that would also boost the British economy.
A date for the wedding has not been revealed but speculation is already mounting over when Prince William and Kate Middleton will marry and is even prompting betrothed couples in Perth to plan to marry on the same day.
"It is going to do fantastic things for the British economy because of the American dollars that will be spent," Ms Dunkley said.
The Victoria League was established 101 years ago to welcome British families to Australia and do charitable work.
Ms Dunkley said despite the perception that the royal family had lost popularity in recent years, a wedding had a different feel.
"Everybody loves a royal wedding and it gives the royal family relevance," she said.
Richard Savage, president of the Australian British Society in WA, said the wedding would breathe fresh life into the British monarchy.
"I'm sure it will be very well received," he said.
Saturday, August 13 is the bookmakers' favourite date for the wedding and this has sparked a rush of demand for that date in WA.
Perth wedding planner Jody Coon, of Jody Q Weddings, said she was stunned to get 15 phone calls yesterday morning from WA couples who wanted to get married on the same day.
She usually received two or three new inquiries a day.
Yesterday, Britain's Daily Mail speculated that Australia was a likely honeymoon destination for the newlyweds because "a second referendum on it becoming a republic is expected, so some feel it would be a diplomatic move to honeymoon there".
