Don't know if you guys have heard of a group called Sydney's Riders?
They have weekly thursday night rides around Sydney and more recently there has been a Saturday night ride as well. Meeting point is at the Shell petrol station at five dock and locations differ each week but generally end with some tasty food! (well the thursday ones do anyway)
Don't see too many Trumpys around which is a shame.
