I am a big supporter of Box of Bikes in Canberra: a family oriented, friendly shop. There are two stores in Canberra, Majura Park and Phillip.
For bikepacking I run a dynamo driven LED lighting system from kLite. It has the additional functionality of charging two AA batteries and can also utilise USB to charge other items such as an iPhone or Garmin.
Check out BikeBagDude for top-quality, Australian made bikepacking bags and accessories.
Warmth & Waterproof Accessories
Sealskinz socks and gloves are amazing and have saved my frozen fingers and toes on so many occasions.
