A state funeral to honour Tim Fischer will be held in the NSW town of Albury next week.
The former deputy prime minister and Nationals leader died aged 73 at the Albury-Wodonga Cancer Centre on August 22, surrounded by close family members.
The government said his state funeral will be held at 1pm on Thursday at the Albury Entertainment Centre.
Members of the public are invited to attend and celebrate Mr Fischer's life.
The former politician led the National Party from 1990 to 1999.
He was crucial to delivering stricter gun control laws after the Port Arthur massacre in 1996, especially as he knew it would be difficult for Nationals members and regional people to accept the change.
Former prime minister John Howard described Mr Fischer, with whom he formed a close governing partnership, as an authentic Australian with an endearing quirkiness.
"People recognised him for being someone who served his country and he dedicated his life to politics," Mr Howard said.
When he retired from politics, Mr Fischer worked tirelessly for many causes, including autism, veterans affairs and agricultural research.
He was also appointed as the Australian Ambassador to the Holy See, and in 2012 he was made a papal knight in recognition of his service.
Tributes followed Mr Fischer's death, including praise by many groups he supported such as farmers, rural doctors and Autism Spectrum Australia.
