Ooh, theres a couple prime locations,
Up Thomas Road from West Perth/Kings Park area, through the medical campuses, up around UWA. Then the Curtin and Murdoch campuses linking to the research park and hospital respectively. Yeah, i can definitely see those.
ECU Perth and Notre Dame are set up already well.
ECU Joondalup could connect better to Joondalup town, and train station, but i don't know why, i feel like this won't work as well as the others. Things feel soo spread out in Joondalup, and that campus felt so separate to everything else when i've been there. Maybe its just that a new place like Joondalup isn't built up as much as older places, so an inner city infrastructure solution like this sounds a bit odd.
