Not sure when you are coming to Canberra but Saturday, 16 March there will be a big fireworks display in Canberra too.
Quote: Thanks Mike L, nothing like local knowledge! I will need to make sure I get to Canberra 2:00pm at the latest the day before so I can check these places out and come up with a strategy on how to move from one location to another and not miss a good photo opp.
Car will be the simplest/fastest way to get to spots on the other side of the lake, at that time of the day you won't have any problems with traffic or parking (for Regatta Point I'd be looking to park in the small carpark on the eastern side of Commonwealth Avenue near the Captain Cook fountain).
Depending on your fitness level it takes 30-45 mins to walk to the other side of the lake.
