"If a referendum is held and the result is a tie, does the Governor-General have a casting vote?"

A referendum is a vote by the Australian people to change the Australian Constitution. Australians are asked if they support or reject a bill (a proposed law) to change the Constitution. A referendum will only be successful if it is supported by a majority of voters in a majority of states, and by a majority of voters across the nation as a whole (a double majority). There cannot be a tie in a referendum—half of the votes is not a majority.
