Your weatherman is right - just because you have winds at the lower end of hurricane force doesn't mean you have had a hurricane.
Where I live we get occasional East Coast lows with winds sometimes as high 150kph which is about the same wind speed as a Category 2 cyclone but it is not a cyclone the sea is not warm enough.
Likewise Tassie is in the roaring forties where winds can get up to 200kph, again hurricane / cyclone force but no one in Tasmania would say they had a cyclone.
A hurricane/cyclone only occurs over water, only between certain latitudes and only when the water is above a certain temperature. It is basically a rotating heat engine.
