Liberal candidate for Mayo Georgina Downer said she was pursuing government support for some priority road projects and other measures on the island.
"Local authorities, businesses and residents have identified several priority projects on my many visits to Kangaroo Island," Ms Downer said.
Ms Downer said the number of tourists coming to South Australia was at an all-time high, and a big proportion of international visitors to the State were heading for Kangaroo Island.
"It's one of the jewels in the State's international tourism crown," she said. "With tourism as a major economic driver on Kangaroo Island, we need to ensure the island's 1600km road network is up to scratch and gets these visitors where they want to go, efficiently and safely.
"I'm inspired by some of the measures introduced on the Great Ocean Road in recent years. More than $100 million has been spent on maintenance, remediation safety and capital works on the route in Victoria with a significant contribution from the Liberal national Government.
"With visitors from China constituting the largest proportion of international tourists to the Great Ocean Road, a good measure introduced recently was a number of multi-lingual electronic signs in English and Mandarin alerting drivers to changed traffic conditions.
