We haven't had enough "help me interpret the road rules" recently. So here's one.
There's an on-ramp from Pacific Highway to Ryde Road where there's a Left Lane Ends sign. To me, it's in a difficult position to notice because it's at a point where drivers are busy navigating a double lane turn & avoiding potential traffic coming in from two other points.
Nonetheless, about 100m later, the lane marking ends. There's no dotted lines to show that the left lane has ended. The central broken line just ends.
The single sign implies that a car in the left line should give way to a car in the right lane. The line markings imply that both lanes have equal rights & whichever car is not ahead should give way.

So, in a situation such as that circled in the 3rd picture above, where the left vehicle is slightly ahead of the right vehicle, who has "right of way" & who should give way?
This. Common sense is don't be a dick when driving. If they're in front of you, give way to them and let them merge in front of you. If they're behind you, then they give way and merge behind you.
