According to the link: "Park at any of Hobart City Council's off-street car parks and take the free Hobart Hopper shuttle. Shuttles connect with Hobart Central, Centrepoint and Argyle Street car parks, where you can park for the first 90 minutes free!"
Of course, in a bike forum, if the buses have a way to transport bikes, you can ride to the bus terminal, load your bike on the bus, then unload at the other end. No need for paying for parking, and no leaving your car in vulnerable park & ride lots.
There are some commuters who drive halfway, then park the car in a park or something and ride the rest of the way.
