Welcome to the Bunnings Workshop community @Large555. It's a pleasure to have you join us, and many thanks for your question about preventing weeds in paving.
You might like to check out these discussions: How to stop growing weeds in between driveway concrete slabs permanently and How to remove weeds in paving joints. There's plenty of great information in them.
I'd suggest using Yates 3L Ready To Use Path Weeder as it's designed to inhibit weeds in paths. Not only does it kill the weeds, but it will prevent them for 12 months. With this product, you'd only need to spray the paving once a year to prevent weeds.
Please let me know if you have any questions.
