Thanks everyone!  Results remain really interesting and fantastic photopoints capturing the current mouth condition.  Interestingly, there's been enough flow to keep the mouth open, but not enough to completely flush the lower depths which still contain some older salty water.  It will be very interesting to see if tomorrow's results have improved the lower depths given we've had a fantastic month of autumn rainfall which has resulted in the first sign of freshwater inflows into our estuaries.  Regards Jarred.

Jarred - thanks everyone for your monitoring.  Results are very interesting, particularly the low D.O, but I believe your values are true and have picked up on an algal bloom.  This is quite common in this part of the estuary, and i've since seen some very high and very low readings over each diurnal (daily) cycle as the algal produces oxygen during sunlight, and then consumes it during darkness!

J.Obst - great water quality and bird observations!  Very distinct salt wedge on the bottom layer which is interesting - shown through Salinity/EC as expected, but also low turbidity down deep due to the clearer nature of sea water vs cloudier freshwater.  Great work!
