Mattoo, 52, the inaugural director of Australia India Institute, was honoured yesterday by Victoria's Governor Alex Chernov during a function attended by India's High Commissioner in Australia Biren Nanda, Consul General in Melbourne Manika Jain and former Australian High Commissioner Peter Varghese.
Chernov highlighted various initiatives of Mattoo which he said were instrumental in deepening and strengthening bilateral ties.
He said the Mattoo's writings had a positive impact on the foreign policies of the two sides.
"I believe it was his (Mattoo) arguments...That paved the way for Australia finally agreeing to sell uranium to India," Chernov said.
