Entry level prices for Rod Laver Arena have been reduced to $62, and the price of a ground pass was frozen at $49 for 2019.
The Minister for Sport, Tourism and Major Events, John Eren, said the government had invested $972 million in the Melbourne Park precinct but did so "because it gives so much back". He said the Australian Open brought an economic impact of $293.2 million in Victoria, with 49 percent of visitors coming from beyond Melbourne and 12 percent from overseas.
The 2019 Open will run from January 14-27 and is the first year of Channel Nine's broadcast of the event.
