Notes:
- Strong flow straight out to sea & also to east
- Water being drawn out of estuary causing large waves to go upstream along channel (channel has steep sides -to .70m. high) , these waves start near the tunnel entrance in an area that has a large shallow water covered sand build up
- Water extremely turbid, sand swirls everywhere & long 'drag' lines are across sand where water has been drawn off
- Mouth wide, rough seas causing waves to surge over top of rocks
- East end of beach still being impacted by SW waves which have created a sheer sand cliff about 1-2m. high
- Very strong longshore drift & rip
- Strong flow downstream at G2 but waves also coming upstream toward bridge
- All areas remain flooded. OOR .80m. near flood markers @ 08:45
channel near boardwalk (also over boardwalk) where algae is starting to form
- Several Portuguese Man o' war along swash line on beach
- 2 large tiger snakes near G2 bridge

- Very strong longshore drift across mouth
- Sand dunes (ocean beach) almost parallel to ocean & smoothed out by wind, beach very flat
- East end scouring out from strong wave surge
- Channel area being impacted by strong south wind blowing sand which is reaching into estuary
- All roads flooded. GOR closed (traffic lights)
- Boardwalk under water , deep water in camp ground, .80m. at flood markers OOR, Ocean Car park partially flooded. Water now on to bridge deck G4.
