According to your link: No. A **double **line must not be crossed either by turning right into the driveway or leaving the driveway to the right.
Only an unbroken (continuous) **single **line may be crossed in this particular situation (entering / leaving road).
Hmm, can you (or someone else) confirm that you are absolutely sure about that?
My friend just sent me an email with the document, which on the bottom of 8th page it is said, I quote: In NSW drivers are also permitted to cross two continuous
lines to enter or leave the road by the shortest route.
