Mr Modi will attend the G20 conference in Brisbane in November and become the first Indian prime minister to address a joint sitting of Parliament in Canberra.
He’s only been in power for five months, but Narendra Modi is already one of the most celebrated and admired prime ministers in India's history.
The 64-year-old started a so-called "new independence" for the country, with many Indians seeing him as a clean-cut economic reformer kick-starting investment.
But in Sydney, Indian Australian Community Foundation spokesman Balesh Singh Dhankhar said there was much more to the man.
"He reflects a common Indian man, he reflects the struggle, he reflects the passion that every Indian person has, and because his journey is so inspiring," he said.
Mr Modi will attend the G20 Leader's Summit in Brisbane on November 15 and 16.
In Canberra, he will address parliament in Hindi, the first Indian prime minister to ever make the address.
It comes after Australian Prime Minister Tony Abbott's recent visit to India, and trade, defence and economic talks will again be on the agenda.
The chairman of the committee welcoming Mr Modi to Australia, Professor Nihal Agar, said Mr Modi was a progressive leader.
"There is no hypocrisy, there is no showing,” he said.
“He says what he believes, and he again does not say something which is beyond the reach of ordinary Indians.”
The visit is not all political, at least on Australia's end.
Mr Modi is making a special Sydney stop, where he will deliver a public address to almost 16,000 Indian-Australians.
More than 21,000 people had registered within three days of tickets becoming available, and Mr Dhankhar said it is a very significant event.
"It's one of the biggest community events Australia will see, especially for a foreign politician,” he said.
“So I would welcome everyone to come and (would) request everyone to visit the website pmvisit.com.au"
Professor Agar said he and his wife Neera were excited.
"We are so fortunate to witness such a great event,” he said.
“I'm looking forward to seeing him, especially hearing him give a speech.”
Security will be tight and logistics will also be a challenge.
However, organisers hope the free event will attract the same attention one held for Mr Modi in New York's Madison Square Garden did.
Mr Dhankhar said a Modi Express train was running from Melbourne for the November 17 event.
"This is one way of reliving those moments when Prime Minister Modi spent years travelling in trains as a grassroots worker," he said.
It will be the first visit an Indian prime minister has made to Australia in almost three decades.
Modi is the second-most popular politician on Twitter, behind US President Barack Obama.
