Polarisation-spatial entanglement in coherent reflected paraxial vector light fields across an infinite dielectric interface, for polarised incidence, is studied. Closed form expressions for the polarisation-spatial entanglement is obtained explicitly in the case of Hermite Gaussian and Laguerre Gaussian modes up to first order approximation, assuming arbitrary state of incident polarisation, angle of incidence, waist width, and mode indices. General observations regarding the polarisation-spatial entanglement which hold true irrespective of the aforementioned parameters are arrived at. It is observed that close to 1 ebit of polarisation-spatial entanglement can be obtained for angles near Brewster's incidence. The feasibility of possible experimental measurement of the entanglement obtained in reflected light fields is discussed through the Laguerre Gaussian mode as an example.
