Almost a year after losing her nephew Adem Crosby to acute lymphoblastic leukaemia, Ms Kello is putting on her wings for the Leukemia Foundation, becoming "an angel" to help others.

She donned the fund-raising wings on Friday in Wollongong and will do so again on Saturday in Shellharbour to not only raise money, but promote the importance of donating blood.

Her nephew needed more than 250 blood transfusions and often had to wait for the blood to be transported.

Raising money has become her passion since Adem's two-year leukaemia battle at age 17 when he was told he had just three months to live.

She was already helping the Leukaemia Foundation when she found herself out of work earlier this year. 

She then decided to take the opportunity to volunteer in the office and aged care facilities.

Ms Kello said the Leukaemia Foundation had provided plenty of emotional and practical support to her family during Adem’s treatment.

‘‘Adem’s wish was for our family to continue to support the Leukaemia Foundation for all the services they provided him and his family such as accommodation, support and counselling and treatment," she said.

‘‘He also wanted us to continue to support the Australian Red Cross blood service.

"We need to continue to find blood donors.’'
