I recently was staying outside Sydney NSW with friends who love on the beautiful Hawkesbury river which flows through Windsor NSW. It’s a pretty litttle town and worth a stop off if you are heading to the blue mountains. Lots of lovely little coffee shops and a few boutique shops.
If you have time hire a boat and take a trip down the Hawkesbury. Some amazing houses to look at from the river plus lots of birds and trees. Or if you water ski it’s perfect.
Windsor is a very old settled town – in Australian terms – not as old as Windsor UK.
