The enforcement would only be in one direction.

The relation 'only' requires one 'device' though in practice here two 
are used.

So it looks fine to me.

overpass turbo can be used to find other relations of this type, there 
are a few around Sydney , Melbourne and one around Albury.

So a minimum time of 10 minutes 27.07 seconds.
At 220 km/h average speed you would need to pull over and wait some 5 
minutes 13.04 seconds to be 'safe' (from a fine).
