After years watching the left hand not talking to the right hand I think I might have the answer...
It was actually the same flight and was delayed for some reason...
The QF ops people had notified the airport operators of the delay and had the amended departure time on the board...
The Jetstar ops people had not got around to notifying anyone of the delay and hence the difference in departure times....![Evil](https://www.pprune.org/images/smilies/evil.gif)

Slightly worrying that in 2009 we still get "but a good operator wouldn't make that mistake, so it's not a problem, besides it were 'arder in my day".
Having said that, flight number callsigns cause the same problem as sequential rego callsigns. FNCs offer the chance to avoid the problem though, and we are not using it.
With regard to same number, different airline, given that crews are listening for the number, and the start of transmissions are often clipped, it's easy to see potential for confusion. (As an aside, how often does Bluey172 call themselves Virgin172?)
In our airspace anyway, Virgin recently changed the range on number they use to match Qantas, and the incidences of confusion went up, unsurprisingly.
Same airline, different number can be as bad. Early afternoon on a weekday we have QFA480, QFA481 and QFA482 on freq simultaneously. Qantas four eighty vs Qantas four eighty one on a slightly iffy frequency, and in a rush?
