Scott Morrison among hundreds at Sydney service to honour Prince Philip

Prime Minister Scott Morrison and NSW Premier Gladys Berejiklian were among hundreds of mourners who gathered to pay their respects to Prince Philip at a memorial service in Sydney.

Mr Morrison was accompanied by his wife Jenny, as well as Governor-General David Hurley and NSW Police Commissioner Mick Fuller at St Andrews Cathedral today on George Street in the CBD.

The cathedral was a well-known place of worship for the Prince, who had previously attended with the Queen on three occasions in 1973, 1977 and 2006.

During the service, The Very Reverend Kanishka de Silva Raffel described Prince Phillip as a "loving husband".

"As we gather, we extend deep sympathy and condolences to Her Majesty The Queen, to whom Prince Philip was, for more than 70 years, a loyal and loving husband," he said.

"On Prince Philip's many visits to Australia, we have come to know him as a man of compassion and service, personal warmth, intellectual curiosity and generous spirit.

"Australians were deeply saddened by his passing, and are praying for the Queen and her family in their grief."

Those in attendance signed a condolence book which will later be passed onto Buckingham Palace by Government House.

Yesterday, a 41-gun salute was held in Canberra to commemorate the Duke's passing, in keeping with tradition being observed by other Commonwealth nations.

Flags also flew at half mast on iconic landmarks around the country, including the Sydney Harbour Bridge and Parliament House in Canberra.

Prince Phillip died at aged 99-years-old, two months shy of his 100th birthday.
