Friends of London Bridge terror victim Kirsty Boden have paid tribute to her strength, bravery and positivity in an emotional memorial service in Sydney.



Surf lifesavers paddled into the ocean off Tamarama Beach and threw sunflowers into the waves as one of her favourite Ed Sheeran songs played on Saturday morning.



The 28-year-old was one of two Australians who was killed in the attack on London Bridge and nearby Borough Market in June.



The 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.



One of her former housemates, Kate Williams, told a gathering of about 100 mourners at the surf club her friend “always had so much love and happiness for another day”.



“I don’t know how to go on, knowing she has become the angel we all knew she was, but the only thing I am holding on to ... is the strength and sheer bravery she had every day of her life,” she said.
