In this work, we proposed a twisted biaxial hyperbolic structure which is composed of α-vanadium pentoxide (α-V2O5) with semi-infinite uniaxial hyperbolic material hexagonal boron nitride (hBN). The two hyperbolic principal axes of α-V2O5 are located within the propagation plane, resulting in some unusual phenomena. We study the transverse Goos–Hänchen (GH) and longitudinal Imbert–Fedorov (IF) shifts on the α-V2O5/hBN hyperbolic metamaterial (HMM) surface theoretically under the incidence of Gaussian beams in three different geometries (Geometry-I, II, and III). By adjusting the thickness of the α-V2O5 film and twist angle of the incident plane, we can obtain the maximum of GH shift about 
. On the other hand, by adjusting the left-handed and right-handed circularly polarized light and the twist angle, the positive and negative symmetry properties of the IF shift can be controlled. The electric field distribution simulated by using Comsol Multiphysics software further verify the above conclusions.
