The cyclists are riding the 2400km from Rockhampton to Canberra to promote a nuclear-free Australia.

In January this year, the Australian Institute released a report citing 19 locations where nuclear reactors could be placed around Australia.

These locations are the basis of the route being taken by the cyclists.

By stopping in these towns along the way, the group is able to meet with communities who would be affected in the event of nuclear power production in Australia.

"There has been a lot of support from local groups up and down the coast," cyclist Georgina Pike said.

The group asks the people to raise their voices and make their opinions to be heard. "It's time for people to be vocal," Georgina said.

"If locals want to keep their area nuclear free, then they need to speak out."

Labor candidate for Paterson Jim Arneman supported the cyclists, saying nuclear power was not welcome in Port Stephens.

"People come to the area for the lifestyle; we don't want that ruined with visual pollution and health risks," Mr Arneman said.
