I see you added a new address for 11 Burrendong Pl at https://www.openstreetmap.org/node/13286395669/history but it already exists at https://www.openstreetmap.org/node/7066252214.

I don't believe we should duplicate it as that leads to ambiguity and it's best to place it at the residence. The routing engine can resolve which street it's accessed from based on the mapped driveway.
