There will be 35,000 Easter eggs, or 170kg of chocolate, for children and parents to consume at a fun family day out on Saturday.
More than 3000 people are expected to roam around the Wollongong Botanic Garden during the Rotary Club of Wollongong's third annual free Easter Family Fun Day from 9am to 12pm.
Wollongong City Council's marketing officer Alison Morgan said children had to complete four activities throughout the garden to receive chocolate eggs during the Easter Eggsploration.
There will be classic family fun games including a sack race and egg and spoon race.
Parents are encouraged to get involved in the activities.
"There will be high-energy games to wear the children out after they have eaten all that chocolate," she said.
"There will also be colouring activities for those children who want a quieter time.
"The event has been overwhelming popular in previous years.
"We want the event to be family focused."
A band from the Wollongong Conservatorium of Music will entertain the crowd from 11am.
The Rotary Club of Wollongong will provide the usual barbecue including sausage sizzle; egg and bacon rolls, hot cross buns, soft drinks and water.
Tea, coffee and ice creams can also be purchased.
There will also be talks on how to keep chickens in the backyard and guided buggy tours where visitors can explore the Garden's 18 collections.
Rotary Club of Wollongong president Dot Hennessy said this year's program was diverse with the events being conducted in many parts of the garden to not only to provide variety in activities but also to take the children, parents, families, visitors to enjoy those areas less familiar and visited.
Friends of the Garden will be supporting the hosting of guided tours including transportation with their people mover.
Ms Morgan said no one had ever missed out on chocolate eggs and she was confident there would be more than enough for those who did not want to attend at 9am.
"I'm sure it will be a lovely day outside where people can breathe in some fresh air, listen to music and of course eat some chocolate," she said.
