Happily, the pictured sign is obeyed by most of the many humans who drive onto Goolwa’s ocean beach, then proceed south…all the way along the Sir Richard Peninsula, to Pullen Spit.
Pullen Spit is the constantly-shifting northern bank of the River Murray’s mouth.
On the southern side of the river mouth is the Younghusband Peninsula, which is 110 kilometres long, but always less than 3 kilometres wide.
The Younghusband Peninsula western side faces the full power of the Southern Ocean; its eastern side is lapped by the Coorong’s much gentler, shallow waters.
The Younghusband Peninsula’s is Australia’s longest coastal dune system, and the peninsula’s ocean side is Australia’s longest beach.
The map below shows the northern section of Coorong National Park; my red squiggle encircles the Murray mouth.
I took the featured image at 10. 46 am on 13 March 2024, as “our” boat sat on the Coorong/rivermouth side of Pullen Spit.
Twenty minutes later we walked onto the Younghusband Peninsula at Godfrey’s Landing, which is clearly marked on the map, above.
