Robertson is only visited if traveling the Moss Vale to Wollongong route. Robertson therefore will not feature on many/any Bustout traverses or planned routes. Robertson is therefore a diversion.
There is not a lot to offer, so try and time a visit with an event. Robertson is active in that regard. Auctions, footy games or even a refreshment crawl could be a sufficient catalyst to make the relatively short journey.
Robertson has several arts and craft shops and galleries, several restaurants and cafes, a hotel and licensed bowling club, one post office, one grocery store. The Cheese Factory was very busy on the Sunday visited. That said the town does have its fair share of essential services.
