Australians are being invited this month to light a balloon at twilight to remember, celebrate and give hope to people living with blood cancers such as leukaemia, lymphoma and myeloma. In Darwin, the balloon lighting ceremony will take place at 6.30pm on 2 September on Liberty Square, next to the Parliament building.
