Can anyone explain why the runway markings in Australia have only the 500', 1000' and 1500' markings. If you land beyond the 1500' markers, you have got no idea how much runway length is left until approaching the other end.
Boeing mandates landing in the first 1/3rd of the runway or 3000' whichever is shorter, this is the end of the runway markings on an ICAO marked runway, but impossible to judge on an Australian marked runway.
Could be a factor in this otherwise unexplainable overrun situations.

I find looking out my window usually lets me know a fair idea of the runway remaining Murdoch_disliker! Not trying (too hard) to be a smart arse, but good grief, how hard do we try and make our job out to be?

I concur with ABC, the more green you see out the front, the less runway remaining.

In the 'Good Ol'e Days" landing beyond the 1500' markers would fail your check ride.

I suggest you have a read of your flight manual to work out how the landing performance is calculated. I'll tell you now, it doesn't allow for a 3000ft-in touchdown!

B737 FCTM 5.5 stabilized approach recommendations: "positioned to make a normal landing in the touchdown zone (the first 3000' or first third of the runway whichever is less)."
Touchdown will occur just before the 1500' markings if following glideslope set for 777, A380, B747 etc (AKL, SYD, MEL etc), therefore many touchdowns are possible beyond this point.
On a 3000m + runway such as MEL 16/34, does everyone really land before the 1500' markers:rolleyes:? I will have a look at the rubber pattern next time I am landing there.
I would prefer something more scientific than "less green in front of me" to assess landing distance available (such as ICAO runway marking system)

But what is your landing performance actually based on?

Who recalls the QF 737 (NG???) that ran off the side of the runway in DRW for about 800 metres during landing run around 2001-2002?? Not much media coverage on that one so maybe not too many people will recall.....I am going purely by memory about an event that had next to no media coverage whatsoever so I am more than happy to be corrected.

The touchdown zone is 1000' to 2000'

At least in CX anyway!!

Some Airfields around the world had "Boeing short field markers" painted on the runway. If you weren't down by them it was a mandatory go around. Tawau in East Malaysia was one in the early 90's.

To be sure

It's going back a while but it did occur (fragemented memory). Not sure if 800 metres was the the actual length, I thought it was around 450 - 550 metres, but regardless it did occur and no it wasn't widely reported by media as lots of other things were happenning within Australian aviation at the time. QF also still had its highly prized safety reputation back then before Darth and the Irishman got their greedy mitts all over the airline so it was likely viewed as a non-event or at least a minor story by the media trolls.

Just out of interest for the Cathay people that have the 1000' to 2000' touchdown zone policy (which I think is a good one). How can you apply that policy in Australia when 2000' markers do not exist? Serious question.
Most short runways will only have markers for 1/3rd of the runway ie Queenstown, Wellington etc about 1800m long, therefore last marker at 600m/2000'.
