Friends of London Bridge terror victim Kirsty Boden have remembered her as someone who never gave up – whether she was chasing her dreams overseas, saving lives as a nurse or running to help others the night she was killed.

The 28-year-old, dubbed the "Angel of London Bridge" for trying to help victims of the June attack before she herself was fatally stabbed, was on Saturday farewelled in an emotional memorial service in Sydney.

Friends paddled into the ocean off Tamarama Beach and threw sunflowers into the waves as one of Ms Boden's favourite Ed Sheeran songs played and up to 100 mourners watched on.

The young nurse, originally from South Australia, had lived and worked in the UK since 2013 but before then spent a number of years in Sydney where she was a volunteer at the Tamarama surf life saving club.
