Cycling in Sydney Australia
Marked as "Bourke Bypass" on the map, mostly unmarked route marked on shared road or shared path.
Worst unmarked is Straight via a left right from Young into a Carpark Lane when South Bound.
It sucks. There's no good way. I've tried a few alternatives, and they're ok, but I usually end up just riding down Bourke St. It's quickest and easiest, and if you take the whole lane is probably at least as safe as any other option, but requires a fair bit of confidence and thick hide to withstand the inevitable road rage.
I usually just ride down the road and it's fine. I assertively take the lane and don't experience any grief from drivers. Watch out for the taxi-drivers coming out of the servo down near Danks Street. They can be a bit cavalier.
Both ways I take the lane (ride where the driver side wheel of a car would be) along Bourke, don't filter and everyone seems pretty happy. Often heading home (south) I get in the right lane before O'Dea (so the left lane can turn left clear of me, I keep up with traffic down hill past the Elizabeth St lights and then already in the right lane to cross Green Square).
I get across onto the Bourke Rd cycleway when I can, but this is usually past Bowden St, ie maybe get onto the path in front of Danoz Direct.
If you can keep up with the traffic (not too hard most of the time as you keep getting reds so just a bit of interval training) and take the lane its a no brainer, but I see others just stay on the foot/shared path from Phillip Street all the way down (again going south) and don't seem to have too much problem, and isn't a lot slower than the vehicle lanes if not filtering. I use the path in torrential rain, only had ti use it 3 times this year.
