It's just off the A2 Autobahn, near the Burgenland-Styria border. Of course, it's more fun to drive the country roads and see all the small towns, forests and mountains.
If you want to use public transport you have the option of train or bus. There are train connections from Graz and Wien Vienna and the railway station is just 15-20 minutes walk from the town centre. Check the timetable but it's probably quicker to use a bus which also go to and from Graz and Wien. The main bus stop is even closer to the town centre, just 5 minutes walk away.
