It is very, very common for one plane to be on approach for a runway while another one is taking off. If the plane taking off is delayed at all, the approaching plane is told to go-around (which is what happened here). Happens all the time.

I haven't read up on this incident, but I suspect the approaching plane wasn't given clearance to land yet, and would have gone around on their own if they hadn't gotten that clearance in time.

Well there are go rounds and there are missed approaches. It appears this was the latter. I can't see how a standard go round involves flying at low altitude directly above a plane that is about to take off or taking off. Obviously planes can approach runways from a distance while others are taking off, it seems here it didn't just approach, but came close to actually landing.

A plane on an instrument approach when told to go around is expected to follow the missed approach procedure. Which 9 out of 10 times includes flying over the runway.

Isn't missed approach procedure to fly runway heading, however not to actually overfly the runway (ie, offset of centerline)?

If you're lined up on the runway, flying "runway heading" will overfly the runway.

Here's the details for the runway in question: https://www.airservicesaustralia.com/aip/current/dap/SSYGL06...

For a visual flight in a small plane that's the way to do it (and then technically runway track instead of heading)

For an instrument flight there is a defined missed approach route that usually includes specific altitudes and turns to get you to some holding position.

Yes there are, and they both use the same procedure.

It got to point where the controller had to give them final clearance to land, or tell them to go-around. Obviously that point is going to be reasonably close to the runway.
