Gabriel first started out in standup comedy in 1996. From 2000 to 2006, Gabriel went on tour with Italo-Australian comic sensation Joe Avati where he visited not only every corner of Australia, but also accompanied Joe on his 3 tours of the UK. While Gabriel was there he also had a go at the mainstream British scene where he enjoyed a great reception, making Gabriel a truly global comedian.

Gabriel can always be seen performing in his home-town Melbourne International Comedy Festival each year.
