When Rotary and the World Health Organisation launched the Global Polio Eradication Initiative in 1988, there were an estimated 350,000 cases of polio, Rotary's End Polio Now campaign website explains.
Since then more than 2.5 billion children have been immunised, thanks to countless volunteer hours and more than $1.7 billion funding.
In 30 years the number of polio-endemic countries has been reduced from 125 to three and polio cases have been reduced by 99.9 per cent.
Rotary's District Governor John Glassford is passionate about completely eradicating polio, and organised the iron lung road trip to raise awareness and funds.
The parade started in Griffith on March 5 and will return there at the end of the month.

The WHO says there is no cure for polio, it can only be prevented by immunisation.
Rotarians are seeking community support to continue to provide vaccines and take them into the parts of the world where polio is still endemic.
