Walter Gors Park

The water play area here is genuinely well-used on a hot day — kids aged roughly 5 to 8 seem to get the most out of the fountains and jets, and there’s enough shade around to make it bearable for parents too. It’s right in the heart of Dee Why, which means you can combine it with a quick grocery run or grab something from the shops nearby without making a whole production out of it. Pack a lunch because the BBQ and picnic tables are solid, and with the pond close by there’s a decent amount to keep little ones occupied beyond just the water feature. Locals know this one — it fills up on weekends for a reason.
