Singer Ronan Keating hosted the Sydney ball with his new girlfriend as his date.
Ronan, who worked with the Australian Cancer Council to make the event happen, has organised Emerald and Ivy Balls in London for seven years.
Last year, at the London Emerald and Ivy Ball, he was accompanied by his wife Yvonne. But all eyes at the Sydney event were on his girlfriend of three months, Strom, who wore a Grecian-style white gown.
Ronan, who is currently filming The X Factor Australia, will host the London Emerald and Ivy Ball in a few weeks.
TV producer Storm is set to move to the UK where she will be working on a new series of The Voice in the UK.
