Ms Bryce's father Norman Strachan was the club's captain in the early 1900s and was a grandson of the pioneering McCauley family, so the visit will be personal too.

Organisers of the anniversary celebrations said Ms Bryce was interested in seeing where her father lived and grew up.

Mr Strachan lived in the Illawarra before moving to Sydney in the 1930s where he worked as a wool classer.

In 1940, Mr Strachan and his schoolteacher wife, Naida, relocated to the town of Ilfracombe in central western Queensland to manage its wool scour and their four daughters - Diana, Quentin Alice Louise, Revelyn and Helene - followed soon after.

When Ms Bryce was eight, the family moved to Launceston and barely a year later to Belmont, east of Brisbane.

The surf club's 100th anniversary celebrations will be held from October 23 to 25 and will include a historic photograph exhibition, surf-lifesaving displays and a dinner party at Anita's Theatre in Thirroul.

Ms Bryce is also making time to open the annual Australian Rose Championships, which will be held at the Kiama Showground Pavilion on October 24 and 25.

The official opening, with Ms Bryce, will be at 2pm on October 24.

Entry to the rose championships, in which gardeners will compete in sections including best cluster roses, best exhibition rose and best miniature rose, costs $3 for adults and $2 for concession card-holders.
