Parking will be very close, as long as the surrounding activity centres aren't too busy. People in wheelchairs will also be able to grab this one as long as the right carpark is empty.
The Bluewater Lagoon is a free family-friendly leisure facility beside the Pioneer River in the Mackay City heart. The three lagoons provide a safe stinger-free swimming environment. Whether you want to avoid the crowds or join them you'll want to know when it's open - May to August, 9am-4.45pm and September to April, 9am-5.45pm (note you don't have to go in the gates to collect the cache).
Happy seeking.
