Flight
Braidwood is around 1.5 hours from the Canberra Airport. We would suggest flying into Canberra (where Lewis was born!) and renting a car with other parties from the wedding. Lewis wanted it known that it has a fantastic War Museum if you have the time!

Alternatively, you can also fly into Sydney Airport and make the beautiful 3.5 hour drive down the coastline then inland to Braidwood.
