Secretary Carol Clark, who has been with the club for about four years, said it had developed over time. 

"We now have a walking group and bike riding group, a camping, caravan and cabin group, and coffee, cake a chatter (group)," she said. 

"There is a range of various activities we do, we have a games morning every now and then." 

Ms Clark said the club had 125 members and offered people something to do to fill in time.  

She said the White Hills Probus club was one of nine groups in Bendigo and the Rotary Club of Bendigo started the club in 1994.   

"We don't always get that many, as you know some people are quite old and not well enough to come, and others have things on," she said. 

"The club is a good way to meet people, who have interests much the same.

"It's also about getting out and about instead of just sitting at home twiddling your thumbs." 

The celebration will take place on March 18 from 10am to 3pm, at the White Hills Sporting Complex in Scott Street, White Hills. 

Former members and other interested people are invited to attend the celebration.

Ms Clark said the club's 20-year history book would be launched at the event. 

She said one of the club's members Esma Turner had written the book. 

"She has been here a long time, and our bulletin editor for a long time," she said. 

"The book includes lots of photos.

"It has been professionally printed and is very good." 

There will be a presentation of life members and 20-year service badges. 

There will also be a series of speakers who will talk about their recollections of the probus club and static displays of various events over the years. 

Lunch and afternoon tea will be included. 

Ms Clark said she expected the event to be well-attended. 

Those interested in attending the celebration should contact Carol Clark on 5449 7099 by February 18.
