. The Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7) is providing integral field spectroscopy on ~140 nearby active galaxies in the wavelength region 3300-7000 Angstroms at resolutions as high as 7000. In this talk, I present the first results of this survey. I show how, by combining data analysis with detailed photoionisation and shock modelling, we are gaining a new understanding of the physics of both Seyfert and LINER galaxies.
