141 No overtaking etc. to the left of a vehicle
(1) A driver (except the rider of a bicycle) must not overtake a vehicle to the left of the vehicle unless—
(2) The rider of a bicycle must not ride past, or overtake, to the left of a vehicle that is turning left and is giving a left change of direction signal.
But I then found in the Australian Road Rules readers' guide:
Use of present tense for some actions
The rules may say that a driver ‘is turning’ at an intersection. The use of the present tense is intended to cover both the present and future aspects of the present tense. That is, it refers to a driver who is preparing to make the turn as well as a driver who is in the course of making the turn. The context will make this clear in the rule.
Now the Australian Road Rules also say:
As a matter of law, the Guide is not part of the Australian Road Rules.
But the Victorian Road Safety Rules say as a note added to section 9A Application of the Acts Interpretation Act 1901 of the Commonwealth
1 Section 95(3C) of the Road Safety Act 1986 provides that regulations may apply Commonwealth interpretation enactments to the interpretation of the
regulations, in whole or part and with or without modifications. However, section 95(3E) provides that this does not prevent the Interpretation of Legislation
Act 1984 from applying to the extent that it can do so consistently with that Commonwealth legislation.
Which I think is my avatar saying that Commonwealth interpretations apply.
I guess the safest thing is to filter to the right of a left indicating vehicle, even if there is a bike lane
