Ok i dont know Graz very Well but i am in Vienna very often for wildlife Photography. In Vienna i can recommend the jewish part of the Central Cementary for example. The Floridsdorfer Waterpark. The Danube Island, and the Perchtoldsdorfer Haide, all these places for animalphotography. But also the Architecture is very beautiful in the center of the City. Schönbrunn, Belvedere, The Parlament, Karls Church.
