Baby Finnigan, who died at two days, and his surviving twin Lachlan were born at 23 weeks gestation three years ago.
The ‘frightening experience’ promoted their mother Amy, of Greenwood, to help set up a State branch of the non-profit group to help others in a similar situation.
Its busy program includes the golf day, annual picnic and a ball.
‘The trophy is in remembrance of all the miracle babies who sadly lost their fight for survival,’ Mrs O’Connor said.
‘Although Finnigan’s story is short, his memory and our love for him will last a lifetime like so many other precious babies who will not get to grow up.’
The four-person ambrose at Mt Lawley Golf Course starts with registration and lunch at 11.30am followed by a 12.30pm tee-off.
Dinner, presentation of awards and a silent auction start at 6pm.
