Engines are revving, fuel levels being checked and tyre pressure tested as final preparations are underway for the Great Endeavour Rally to pass through Dubbo.
The charity car rally will pull into Taronga Western Plains Zoo for a lunch time stop on Wednesday, June 20, while travelling between Collerreina Hall and Ballimore.
Now in its 31st year, the charity car rally raises funds for the not-for-profit Endeavour Foundation.
The rally sets off from the Gold Coast on June 16, and eight days later participants will finish their 3200km Great Southern Safari.
This year 130 people in 45 vehicles will participate including support from the Army.
Rally Coordinator Nathan Woolhouse said participants had helped improve the lives of people with disability around Australia.
“Endeavour Foundation offers education, training, employment, accommodation, respite and recreation options for people with disability and over the years funds from the rally have supported all of these things,” Mr Woolhouse said.
