The next day, we went for another walk along the river front at Renmark and then drove to Mildura in Victoria. On arrival, we discovered that we'd forgotten a backpack so Robert drove all the way back to Renmark - a 300km round trip!  

Meanwhile, Margaret wandered around Mildura which is a large town on the border of Victoria and New South Wales. It's laid out on a grid system with very wide streets - similar to Renmark. Mildura is also on the banks of the Murray and is also a large growing region, thanks to irrigation from the river. So, lots more vineyards and orchards. 

The next day (7 March), we drove around Mildura to see the recommended sights. We went to Wentworth which is at the confluence of the Murray and Darling Rivers. There is a definite line between the rivers as they merge - the Darling carries a lot of clay and is sandy in colour whilst the Murray is blue.   

Whilst there, we went to see the Perry Sandhills which are 12m high and cover an area of 400 acres. Based on fossils and bones, they've been calculated to be over 50,000 years old with some of the lower levels 100,000 years old. Apparently, the Murray and Darling rivers used to be much fuller and carried a lot of sand. When the water levels dropped, the sand was deposited and subsequently blown by the wind to form the sandhills.  

We also visited HM Wentworth Gaol which was operational from mid 1800s to 1927. It was smaller than Fremantle Prison but it's well-preserved and was interesting to visit.  

From Wentworth, we drove around the locality through Buronga (which boasts the first semi-arid botanical garden in the southern hemisphere), Gol Gol (which claims to be a gorgeous town), Irymple (which is where the Mildura Irrigation Settlement began) and other unremarkable places. We decided the tourism sites use superlatives rather too freely!!
