I also went today and guess who bumped into me? Wasn't sure at first but yes it was Dick Smith himself. Wasn't expecting that.
Agree, the volunteers were just awesome and the Bureau of Meteorology stand was the friendliest.
Really enjoyed the engagement this year by the people of the Australian forces, however I didn't get a chance to do my favourite chats with the yanks who just love coming down here. Unfortunately after doing a helicopter virtual reality sim I came out of it with severe motion sickness and the heat wasn't helping. I had to pull the plug and leave early.
