A new AU$40 million package from the Victorian government will deliver free Wi-Fi on V/Line's newest V/Locity trains from Melbourne to Geelong, Bendigo, Ballarat, Seymour and Traralgon, along with improved mobile reception along rail corridors.
Premier Denis Napthine said the government will seek expressions of interest to install the free service, which he said will be ready by the end of next year.
"It's a great new service for commuters and a great thing for populations in rural and regional areas," Dr Napthine said.
Part of the package will be used to improve mobile coverage in bushfire-prone areas, which Dr Napthine said had hampered the issuing of warnings and community response to fires in the past.
"It will hopefully be complemented by funding out of the the AU$100 million commitment of the federal coalition government to fix mobile blackspots across Australia," he said.
"We are certainly putting a strong case for our share of that money, which we estimate will be AU$25 million."
The government has already announced free Wi-Fi in central Melbourne and the Geelong, Bendigo and Ballarat CBDs.
