In this paper we present the results of VLBI observations of six radio galaxies belonging to the 2-Jy sample. The selected objects are 3C 17, PKS 0620-52, PKS 0625-35, PKS 1318-43, PKS 1333-33 and 3C 317. The first is a high power radio galaxy and the remainder are all low power objects. Our observations were carried out with a set of different arrays and frequencies, and cover a range of resolutions from a few mas to a few tens of mas. Parsec-scale images are presented and discussed in the light of unification for radio loud galaxies. Estimates for the intrinsic plasma speeds in these objects in the proximity of the parsec-scale core and their orientation to the line of sight are in agreement with the predictions from unified models and with their optical and X-ray properties. We will use H₀=50km/s/Mpc, q₀=0 and S∝ν^–α throughout the paper.
