In North America the day will be lovely and hot being the middle of their Summer, out here in Australia it is the middle of Winter in what many people like to say is one of the coldest spots in Victoria!
Well, if you wear some warm clothes it should be quite nice!
There are BBQ's outside with no cover, so if it is raining you might not want to use them.
There is a big rotunda for shelter and a playground for the kids.
The gardens are also quite lovely to walk around, we often come here for picnics in the warmer weather.
Looking foward to seeing you there.
