What do you mean "these spiral events"? There was more than one?
Obviously if an object is high enough it can be seen by the whole country, especially on a cloudless sky.

I hope you realise the land mass of this country its not Malta

Orbital launches are almost always made in an easterly direction in order to take advantage of the Earth's rotation for a velocity boost. This one was no exception as can be seen in the videos of the launch.
I agree about visibility. The key to the visibility of this event is the same as being able to see most any event in orbit. The object is high enough to be illuminated by sunlight while the vantage point is still in darkness (or semi-darkness). A happy coincidence of timing.

I can buy the rocket then (dad was a rocket scientist) but why spiral crap all of a sudden?
These look awfully controlled...I can't imagine the science behind controlling roll like that? My dad told me we sent men to the moon on 64k computers, so no wonder what we can do today...but still.
It looks a little TOO controlled to be a rocket...although, that IS what I have to side with for the time being.
Still doesn't explain why we're seeing these now when we've been testing rockets for decades. Maybe a new booster technology? Maybe spirals are easier or more fuel efficient for controlling vectors/trajectories?

The Falcon is a two stage rocket. The first stage was dropped over the Atlantic. The second stage takes the payload into orbit. Once in orbit there is no hurry to separate the payload (the Dragon mockup) from the second stage. In fact, being the first orbital flight, it is reasonable to assume that they would have waited until the spacecraft was within tracking range of Woomera to perform the separation.
All Falcon designs had only two stages and only one stage separation event – the minimum practical. All stage separation bolts were all dual initiated, fully space qualified, and had a zero failure track record in prior launch vehicles.

ok....as I was typing previous post... Channel 9 Sydney just gave an update of the top stories for news at 6pm.
They are going to cover the event. Layla McKinnon (newsreader/journo) said "you won't believe what it turned out to be".
Hmmm

Am I correct in my understanding that there is actually NO physical 2nd stage separation once the 2nd stage motors have been shut down ?
...mmmmkkkk...I'll have to read up on that...
