to be really pedantic "two entrances" could easily be interpreted to mean TWO FRONT DOORS which you already have? The intent being that access to the second dwelling is not through the first.
where in the DA or Council's LEP is the requirement taht two entrances means TWO DRIVEWAYS? In terms of units this would equate to q driveway for each unit which would be silly
