[1][2] Quantock is known for his pioneering style of stand-up comedy, which is often politically driven, as well as being the face of bed retailer Capt'n Snooze for many years.

Described as "a living Melbourne treasure" by The Age newspaper, he has also achieved great prominence with his involvement in political activism and social justice and as a speaker at many public and corporate events.

Quantock became more involved in television in the early 80s and the 90s, working on the series Ratbags, Australia You're Standing In It, Fast Forward, Denton,[3] BackBerner and was a regular on The Big Gig and Good News Week.

In a working relationship spanning 18 years, Quantock explains that there were "a lot of things about Capt'n Snooze that were good and a lot of things that were bad"[8] but concedes that his main reason for continuing to be the face of Capt'n Snooze was financial:They said, "All you've got to do is wear a little nightshirt and put a hat on and jump up and down on beds and you can have that semi-trailer full of money".

The success of the bus tour depended largely on the element of surprise and the results, which sometimes included holding a mock house sale auction, were almost always comical.

[7] From 1989–1994, Quantock was a weekly columnist for the Sunday Age[7] and in September 1999, Double Disillusion, a compilation book of these columns and some of his live performances, was published.
