We investigate a sample of 40 local, main-sequence, edge-on disc galaxies using integral field spectroscopy with the Sydney-AAO Multi-object Integral field spectrograph (SAMI) Galaxy Survey to understand the link between properties of the extraplanar gas and their host galaxies. The kinematics properties of the extraplanar gas, including velocity asymmetries and increased dispersion, are used to differentiate galaxies hosting large-scale galactic winds from those dominated by the extended diffuse ionized gas. We find rather that a spectrum of diffuse gas-dominated to wind-dominated galaxies exist. The wind-dominated galaxies span a wide range of star formation rates (SFRs; -1 a parts per thousand(2) log (SFR/M-aS (TM) yr(-1)) a parts per thousand(2) 0.5) across the whole stellar mass range of the sample (8.5 a parts per thousand(2) log (M-*/M-aS (TM)) a parts per thousand(2) 11). The wind galaxies also span a wide range in SFR surface densities (10(- 3)-10(- 1.5) M-aS (TM) yr(- 1) kpc(- 2)) that is much ...
