I would be loathe to take this further than family Ectobiidae, as it looks like an immature. I fully grown one might be easier.

Is there a chance this could be Robshelfordia simplex as recently spotted in Sherwood Forest? The patterning looks right and the Cercus look like they are pointing upward which I believe is a trait of the species.
There are a few others placed in Ectobiidae sp. (family) which I also think might be Robshelfordia simplex. Rentz Guide to Cockroaches of Australia does place a population of this species in eastern Australia despite the name of Shelfords Western Cockroach.

I agree that it is Robshelfordia sp. See conversation on sighting 4347075:- Robshelfordia sp. (genus) (A Shelford cockroach)
We could be confident to ID the other Ectobiidae sp. (family) I have submitted as Robshelfordia sp.
