Hi Jeff,
I am a volunteer with Shoalhaven Marine Rescue. There were some very strange currents in the Shoalhaven River at different places, other places were almost unaffected. If you have a look at the attached graph of River Heights at Greenwell Point issued by BOM, you can see that it is basically missing a high tide cycle late on Sunday night.

At about 8:30am Sunday Morning in Shores Creek (adjacent to Greenwell Point) where both Marine Rescue boats are moored and tide flow normally fairly minimal, the tide should have been running in and it was actually running out at 5 knots plus. Couldn't get either rescue boat alongside the wharf at Crookhaven Heads as the current just drove both boats sideways at 100mph, yet no problem at Greenwell Point Wharf. The pleasing thing was that no boats headed off shore from the Shoalhaven River, where there would normally be 12+ go out at this time of year. The sad thing was that 15+ boats went offshore from Batemans Bay, 10+ went offshore from Ulladalla and about 8 went offshore from Jervis Bay.
Cheers
