Both the river trade and heavy construction (locks, bridges,
barrages etc) all used paddleboat/barge combinations.

Should have added: new heavy constuction, eg the fmed Hindmarsh
Island Bridge, had a baby tug for pushing pontoons etc around.

The dredges at the Murray Mouth (useless devices) are small
self-propelled barge-mounted suction dredges, no tug needed.
