Barragal Lagoon 
From Francis Barrallier journal :-
John Warby convict member of the party.
“On the 6th November, 1802, I crossed the river Nepean, at a ford called Binheny by the natives. The banks of this river, although being too high to allow my team to cross over with the waggon, were quite practicable for men on foot, its depth being then about 2 ft. on the eastern bank, diminishing gradually to 3 or 4 in. on the opposite bank. * [Footnote – * The bottom of this river is composed of very fine sand which retains the imprint and the form of the undulations of the water. It was thought, on the faith of groundless reports emanating from several persons, that the crossing of this river was very dangerous on account of the quick-sand with which they pretended its bed was formed; but I never experienced any danger whilst crossing it beyond a sinking under my feet of 3 or 4 in.]
“I was therefore obliged to have my bullocks unyoked and to have the provisions, as well as the waggon itself, carried by some men on to the other bank, carried by my men on to the other bank, whence, everything having been replaced in its proper order, I directed my route towards the south-west. I continued to walk in that direction, and at 8 o’clock, I arrived near a swamp, which the natives call Baraggel, where I decided to spend the night, feeling rather indisposed. I explored the borders of the swamp, and I found several rare shells belonging to a species I had never seen before. I had walked 4 miles on a flat and open country.
