Delivering the annual Gandhi oration, Justice Michael Kirby considered how Ghandi might have responded to the Delhi bus rape case and women's rights.
And in his typical provocative style, the honourable Mr Kirby didn't shy away from another extremely sensitive topic - the issue of Gandhi's sexuality.
Correspondent: Will Ockenden
Speakers: Arun Goel, Indian consul-general in Australia; The Honourable Michael Kirby, former Justice of the High Court
OCKENDEN: (Indian Music) More than 1,000 people turned out in Sydney to remember the man known as the father of the Indian nation.
Among them the Indian consul-general Arun Goel.
GOEL: Just as commemoration of the ideals and the teachings which Mahatma Gandhi stood for, as they have universal appeal.
OCKENDEN: It was standing room only as the former justice of the High Court, the Honourable Michael Kirby, delivered the annual Gandhi Oration.
KIRBY: Fallible, humorous, witty, playful, determined, sometimes ruthless, unpredictable, rabble-rouser, guru. Occasionally misguided, deeply spiritual - a human, like the rest of us.
OCKENDEN: Michael Kirby speculated on how the revered and complex character would view today's issues - including the recent gang rape of a young woman on a Delhi bus.
KIRBY: What would Gandhi, father of the nation, have said about such an offence, save to condemn the brutality and disrespect for women that it evidenced?
Gandhi wrote a great deal about women and about their role in the India that he hoped for.
Thus he said, "I am firmly of an opinion that India's salvation depends on the sacrifice and enlightenment of her women."
OCKENDEN: Michael Kirby said Ghandi might have asked Indians to consider some of the reasons why so many decades later, many women were still struggling for respect, quoting research which found:
KIRBY: At the turn of the millennium, Indian census figures showed 111 boys born for every 100 girls.
OCKENDEN: Michael Kirby saved his most controversial issue for the end of this speech - the nature of the guru's relationship with his friend Hermann Kallenbach.
But Michael Kirby said there was no doubt it was an intimate one.
He drew on letters Gandhi wrote to Kallenbach, in which he referred to Vaseline being a constant reminder of his friend.
KIRBY: But in earlier times Vaseline and long after was commonly used by heterosexuals and homosexuals for sexual purposes. A century on, who can tell what Gandhi meant.
OCKENDEN: Michael Kirby ended the speech by saying Gandhi's central message was to challenge, to disturb, and to shake us out of our complacency.
It's a philosophy the Honourable Michael Kirby himself has always lived by.
