Upon reading the Wiki article you will find this "This method enables the Rollbock wagons to traverse curves as sharp as 15 m (49.2 ft) radius and, when fully loaded, they could be moved over narrow gauge tracks at a safe speed of 13 mph or 21 km/h"
Yes, designed for gauges of between 600mm and metre gauge, mostly.

In the 1950s, Commonwealth Railways operated a piggyback by the train load using ordinary flat waggons fitted with CWR rails on top. NG trains were loaded onto SG trains.

This was between Port Augusta and Beltana, perhaps 100km? The Rollbock lines are probably very short, say 20km.

There are no tunnels on this section, and few if any low overbridges to constrict the loading gauge.

What speed could these trains operate at?

The CR SG ran from Stirling North to Marree. The narrow gauge when north from Marree.
The distance is approximately 360kms. Beltana to Stirling North is about 200kms
There were no tunnels or overbridges on the line

These "piggy back" trains allowed NG rolling stock and Locos to be moved to and from Port Augusta workshops for repairs.
Most freight was transhipped between the NG & SG at Marree.

Speeds on the well maintained SG line would have been at least 80kph possible up to 100kph

No. During the gauge conversion, once the standard gauge reached Brachina, about 140 km from Stirling North, whole narrow gauge coal trains from Leigh Creek were moved onto standard gauge flatcars piggyback style to complete the trip from Brachina to Stirling North. This was significantly faster than running via Quorn and the Pichi Richi pass.
