Bourke is on the list for the Royal Flying Doctor Service's (RFDS) South Eastern Section's Outback Car Trek this year on 31 May. 

Each year hundreds of antique car lovers manouveur their vehicles several thousands of kilometres through the outback to raise money for the RFDS. 

This year's route starts in Bathurst on 29 May and finishes in Cairns on 8 June, making the trip 3,800 kilometres long.

Over 240 motorists are coming along for the ride this year.

The route changes every year but Bourke has always been a fan favourite. 

"Bourke was included in this year's trek route, as it has become a favourite destination over the years," retiring CEO of the Outback Car Trek Bill Patrick said.

"It has lots of history, holds a significant place in the development of NSW during the 1800s and early 1900s, and has a great many facilities not least of which is mechanical workshops and nice warm motel rooms."

Since its inception, the Outback Car Trek has gathered over $36 million for the RFDS which provides essential medical services to many rural communities. 

Over a third of the RFDS South Eastern Section's funding comes from donations. 

To participate in the trek, the car must be over 30 years old and undergo safety checks and specific strengthening including strong front ends and engine bash plates. 

Most cars are coated in bright paint but the dog team, consisting of a dog, pup, mutt, and dog catcher, stands out by covering the vehicle in fur.

Normally the trek is one week long but every five years, including this year, the trek is extended to 11 or 12 days. 

"It allows us to get to even more far-flung destinations," Mr Patrick said. 

The Outback Car Trek not only raises donations for the RFDS but also helps boost the local economy of the towns they visit. 

According to the organisation, at each stop-off point trekkers spend a total of $75,000 on food, fuel, accommodation, and mechanical repairs. 

Throughout the entire trek, participants also donate up to $100,000 for local initiatives such as schools and community projects.
