William Snow otherwise known as Bill or Billy was an anti-smoking activist, a co-founder of BUGA UP (Billboard Utilising Graffitists Against Unhealthy Promotions) and contributor to the banning of tobacco advertising and the realisation of a smoke-free environment in Australia.

In addition to his anti-smoking activities, he was an avid campaigner against nuclear weapons and destruction of the environment and was a strong supporter of Aboriginal Rights.

He grew up in Drummoyne and attended Fort Street High School where he won an award for debating and graduated with the leaving certificate.

Billy began work as a printer’s mechanic and rebelled against his strict Salvation Army upbringing by immersing himself in the early Rock 'n' Roll scene.

He sailed through SE Asia and the Mediterranean and travelled the length of the Americas, working as a printer in Japan, London and San Francisco.

In 1978 Simon Chapman, and others involved in public health who, concerned about tobacco advertising, formed a group called MOP UP (Movement Opposed to the Promotion of Unhealthy Products) but after the meeting Bill, Geoff Coleman and Ric Bolzan decided that direct action would be more effective using satire on billboards, linked by the simple words BUGA UP (Billboard Utilising Graffitists Against Unhealthy Promotions).

Favouring preventive action at all levels, he would visit Police stations with leaflets and explain to the somewhat startled officers that BUGA UP was to be active in their area and it would be appreciated if the health activists were just allowed to get on with the job.

But the fact that this happened made BUGA UP the most radical health promotion group in the world, which served to make all other anti-tobacco actions moderate, and re-frame the debate globally.
