The edge of the shadow will take less than two minutes to travel the approx 450km from the west coast of Cape York to the east coast with an average speed of approx 16,000 kph.
The high speed is because the sunlight (or in this case the absence of it) is at such a shallow angle to the edge of the earth - it being not long after sunrise. Later in the eclipse when the sun is higher in the sky, the speed over the ground (ocean) will be much slower.
