אוסטרליה היתה המדינה הראשונה בעולם שחוקקה חוק המחייב את כל רוכבי האופניים לחבוש קסדה. החוק נחקק בסוף שנת 1990 והחל להיאכף בתחילת חודש יולי 1992.
האתר cycle-helmets.com אשר מנוהל על ידי חוקר אוסטרלי, מרכז נתונים ומידע רב על השפעת חוק הקסדה. להלן מספר קישורים לחלק מדפי האתר, אשר מתוכם עולה שחוק הקסדה גרם לירידה במספר רוכבי אופניים וכתוצאה מכך לירידה בבטיחות רוכבי האופניים:
Analysis of results in Western Australia suggests the helmet legislation has:
This page has tables showing cycling numbers in the nine months pre-helmet law and since in Perth, Western Australia. It also has summaries and download links for numerous studies re cyclist numbers across Australia.
Submission to draft National Road Safety Strategy 2011-2020 (submmisson 1 to NRSS, submission 3 to NRSS)
These are two of the pages sumitted to the Australian NRSS during 2011. Completely ignored by the authorities. The first page uses Australian Bureau of Statistics data from 1985/86 re cyclist numbers per day across Australia, different states and cities, and compares it with various surveys since the law was introduced. Note that cycling popularity was reportedly increasing by about 10% per annum in the 1980s, so cyclist numbers were probably quite a bit higher than the 85/86 ABS data by the time the helmet law was first introduced in 1990.
The second page considers all road user accidents/injuries, including car vs car, when tens or hundreds of thousands of discouraged cyclists instead drove their vehicles. This analysis seems to go down like a lead balloon with other helmet law researchers. The stats show a steady decline in Australian road casualties before the introduction of helmet laws in 1990/92, after which casualties increased significantly. The assertion might be controversial, but it's a powerful and logical argument with supporting evidence - less cyclists = more car drivers = greater traffic density = more accidents = more chance everybody is at increased risk of injury, whether or not they ride a bike.
Critique of NSW study
This page was written by Chris Gillham in defence of a published study by Chris Rissel, The impact of compulsory cycle helmet legislation on cyclist head injuries in New South Wales, Australia. The page has lots of evidence and supporting graphs.
Mandatory bicycle helmet law in New Zealand
New Zealand is the only country apart from Australia which actively enforces mandatory all-age bicycle helmet laws nationally (although adults are exempt in the Northern Territory of Australia). The law was enforced in New Zealand in January 1994.
The cities of Melbourne and Brisbane were the first in Australia to introduce bicycle hire schemes in mid-2010, despite advice that they would fail if customers are forced by law to wear helmets.
This page chronicles the introduction of bike hire schemes since 2007 in different cities around the world where authorities have acted to counter high fuel prices, traffic congestion, road casualties and carbon pollution while at the same time promoting healthy exercise among citizens.
Bike hire schemes in the two Australian cities have been a flop since their introduction, with mandatory helmet laws the clear reason..
