A crowd of about 30,000 people packed out Melbourne's Marvel Stadium on Thursday night for the public engagement with Narendra Modi.
With Indian dancers performing inside, human rights protesters outside the stadium were drowned out by those waiting in line for their tickets to the sold-out event, who shouted over them a chant of "Modi, Modi".
The event presented a rare opportunity, Vineela Paladugu told AAP.
"If I'm in India, going to see Modi out of the 100 million people over there, it's not going to be possible," she said.
"So when you get an opportunity like this, you just come and use it."
Arnab Ghoshroy said despite living in Australia for the past 20 years and making the country his home, his connection to India was strong.
"I'm part of Melbourne. Melbourne is my city, my home," he told AAP.
"But of course I have a strong connection to India too.
"I'm born in that country. I'm part of India still - Indian diaspora."
Earlier on Thursday, Prime Minister Anthony Albanese and his Indian counterpart signed a swathe of deals.
Uranium will be shipped from Australia to India, ending more than a decade of delays to regular shipments of the fuel.
Australia and India signed a civil nuclear deal in 2014, though regular shipments of uranium haven't occurred amid concerns the fuel could be used for weapons.
"While we are separated by an ocean, we are indeed the closest of friends," Mr Albanese said of the countries that are six years into a comprehensive strategic partnership.
"Australia's relationship with India has never been more consequential than it is today."
The Greens warned the uranium export deal, which Mr Albanese initially opposed, should not have been signed given India's stance on nuclear weapons, while Pauline Hanson deemed the move "hypocritical".
"Labor's energy hypocrisy knows no bounds. They ban nuclear energy in Australia but happily export uranium for this purpose overseas," she said in a statement.
A joint maritime security road map has also been endorsed by Mr Albanese and Mr Modi, along with plans to boost the coast guards of both nations.
Australia's Cocos Keeling Islands, which sit largely untouched in the Indian Ocean, will be used for a temporary space-tracking terminal as part of India's space plans.
Further education deals were announced, including approval for a Flinders University campus in India and increased Australian vocational programs in the Asian nation.
In 2026, 41 projects will receive $10 million worth of funding through the Centre for Australia-India Relations.
Mr Modi said a "common world view" helped India and Australia continue moving forward with deep trust for each other, particularly in sharing education.
That view was also shared with Canada, which will join a three-way technology and innovation partnership for work on emerging technologies including artificial intelligence.
Human rights groups such as Amnesty International have condemned Mr Modi for declines in India's living standards and for targeting journalists and academics through anti-terror legislation.
Marginal religious groups including Muslims and Christians have also been targeted.
The Australian Federal Police formally warned a young person who had made a death threat towards Mr Modi ahead of his arrival in Australia.
A far-right influencer also gatecrashed the Melbourne hotel where the Indian prime minister was staying, before being thrown out by police.
He posted a video of his late-night tirade where he yelled "f*** Modi" in the hotel's lobby.
