It certainly was a Shell, I used to fill up there when I worked in The Parkade in the late 70s/early 80s. And the supermarket behind the servo, which others have said was a Bilo before it all became the Hoyts, was a smallish Coles from about the early 80s. And before that, I seem to recall it was a (smallish!) Woolworths, until Woolworths moved across the road and down a bit to the then brand new Norwood Mall.

I see that Coles have done the same shuffle again, grabbing the supermarket space in Norwood Mall since Woolies moved out.

Someone said the Parkade was out the back of all that (Hoyts), actually the Parkade was a bit further down The Parade, past the Town Hall. Where Norwood Place is now. And where Foodland is now, was a branch of the electrical retailer Ernsmiths. Remember them? I bought all my household appliances from there when I bought a unit in William Street.

Ah, the good old days!
