I would be surprised if golden syrup needed refrigeration after opening. It's similar, after all, to corn syrup or maple syrup or molasses (treacle), none of which need refrigeration. Sugar is actually a preservative, so as long as you keep the bottle closed or cover the tin with plastic film to keep the air out it should last for quite some time!
Maple syrup, once opened, needs to be refrigerated, otherwise it will mold.
