This is a new vessel, and is exploiting very high river levels to make an unusual maiden voyage.
...new paddle boat, 'Bungunyah', recently launched (~Oct.10) and with one short maiden voyage under her belt. Bungunyah is the name given to the ancestoral inland lake which was formed by the Pinaroo block uplift...
I am finding it very hard to locate an online map which makes the river geography clear.

www.murrayriver.com.au/river-management/murray-darling-basin-commission/The vessel had been moored at Beveridge Island, Murray River, downstream of Swan Hill.
It set forth in December, downstream (requiring Nyah Bridge to be lifted, and probably Tooleybuc too), and turned right into Wakool River, then upstream 28 km to Kyalite. This town once had a rolling bascule bridge, as both the Wakool and Edward rivers were navigable to Deniliquin, and right through to where they left the Murray as anabranches. Wakool River was the original Murray course, and has a noble bed, normally with very little water. The Murray which we know today was formed when a geographical fault caused a diversion via Barmah Choke to join Goulburn River.
I don't know if the vessel snuck up a further 4 km to the confluence of the Edward and Wakool (I did that on Wed.29.12).
Today (Sun.2.1) it is setting out down the Wakool, back into the Murray, and on to the Murrumbidgee junction, then up the Murrumbidgee to Balranald.
This will make it the first paddleboat there for 50 years. Back in the days, the river was navigable to Balranald and Wagga Wagga in most seasons, and to Gundagai occasionally. The swing bridge at Balranald has been replaced with a low-level road bridge. Although the water is at flood level for voyaging clear of snags, the boat will be unable to proceed further (there are also weirs at Maude and at Redbank).
Footnote: That type of bascule bridge is known as the Coraki type (named after the location of the first one built in NSW). The counterweight for the hinged span rolls down the curved track on the adjacent span. The Kyalite one was built in 1912. It seems to have been a modification of an earlier fixed-height bridge.
