"Since Modiji has travelled a lot by trains as a grassroots BJP worker, we came up with this idea," said Modi fan Sanjeev Bhakri.
"We have plans to put up Modiji's banners and enjoy Gujarati food during our journey," said another Modi fan, Vijeth Shetty.
Dhankhar said people were "enthusiastic about watching the charismatic Modi live in front of thousands of people who will congregate at Sydney's Allphones Arena Nov 17".
He said that while planning Modi's Australian tour, it was believed that the Brisbane visit for the G20 summit, the parliament address in Canberra, and Prime Minister Tony Abbott's banquet at the Melbourne Cricket Ground would be enough.
