That just seems to be the Brisbane times sensationalising. Later in the article posted in the OP:

The committee recommended any device that did not meet the EN15194 standard for a legal e-bike with assistance cutting out at 25km/h should be defined as a motorbike, and riders would need a motorbike licence, registration, a VIN, CTP insurance, and only ride on roads, not paths.

Recommendation 19 says e-mobility devices for on-road use should align with the EN15194 standard – with a 25km/h limit and maximum 250-watt motor – and devices sold for private property only should be permanently marked.

The people interviewed in the article may not even be affected.

These just seem to be committee recommendations, too, and are nowhere near being a law. The 10km/h speed limit thing will go nowhere.
