When I'm not hacking I spend most of my spare time playing sport and music. In the winter I play rugby for Forest Rugby Club and enjoy snowboarding. Throughout the year I can be found swimming, cycling or practicing gymnastics. I sing bass in the Inner West Voices choir and dabble in guitar and piano. I also own and operate a Roland Ax-Synth keytar.
