The wider internet access is due to a partnership between Parks Australia and the ACT Governments' CBRfree Wi-Fi network.

Built in partnership with iiNet, CBRfree is one of Australia's largest free outdoor public Wi-Fi networks.

Wi-Fi going bush was a part of the gardens' 20-year master plan, according to general manager Peter Byron.

"A key focus of the plan is to enhance the range of visitor experiences and thanks to our ACT government partners and the CBRfree Wi-Fi initiative we are certainly on track to make this happen," he said.

"We are excited to see more students, more tourists and more locals visit the gardens and share their experience in real time with just a click of a button."

ACT Minister for Small Business Chris Bourke said there had been a phenomenal take up of CBRfree in the locations.

"The community has shown that free public Wi-Fi in our major town centres and popular venues is highly sought-after, with an average of 20,000 unique users per week logging on across the city," Dr Bourke said.

"We are so pleased to have partnered with Parks Australia to bring CBRfree to the Australian National Botanic Gardens. Not only is this a great service for visitors to enjoy, but by rolling out CBRfree in the Gardens we have also increased coverage across the CBD."

CBRfree is now live in Civic East, Civic West, Dickson, Manuka, Belconnen and the Kingston Foreshore and will be joined by Gungahlin, Weston Creek and Woden "soon".
