Looking at the orientation of the aircraft in the daylight pics, in relation to the ground markings shown in the overhead shot, I don't think he made a beeline for the bay as per the proposed dotted route. The nose is too far to the left in actuality. I think they mistook TWY J for the apron edge taxiway, then turned left to head to the bay as if they were on the apron.
That's because lead out lines:
These guys weren't taxying out, they were taxying in. Lead in lines always take you all the way there.
where the lead out lines don’t lead to anywhere and you’re forced to make your own way over to the correct line. No doubt the crew had done a bit of this and it normalises not following the lines
must extend to a point from where the pilot can clearly see the taxi guideline.
They don't have to take you there. If you look at the overhead of Rocky, the lead out lines don't take you to a taxi lane either, but pilots taxying out don't end up in the grass strangely.These guys weren't taxying out, they were taxying in. Lead in lines always take you all the way there.
Yes, that’s true. I was more talking about the normalisation of taxiing without being on a line. As for your quote of the purpose of lead out lines, Brisbane seems to have applied this in an academic rather than a practical manner.

Incidentally, -NXH seems to be planned to work YBBN-YBMA return in a few minutes...So whatever damage was incurred can't have been too major or the engineers managed to get their checks done at Rocky...

Only half a speed-brake

(not disputing this crew was facing straight in, so even a good habit could kick early to their detriment)

I've just measured on Google Earth a regular bay I go in to and where I normally turn the lights off....

Doing exactly that would have lined up the solely responsible PIC for the wet grass here, agreed. The daytime picture also got me thinking why so far in, not just the NW and stop, could they not see the grass once in it already? Perhaps not.
My scream was about colleagues rushing to close the taxi lights like their paycheck depended on it, irrelevant to the topic.

I though the ATSB was going to look into this one but doesn’t seem to be on their web site. Is this investigation going to be internal and therefore likely not publicly released?
One would hope that ATSB has more important things to address, like perhaps Australia’s alternate aerodrome policy for domestic operators.
Perhaps mud on wheels is not considered to be damage, and bruised pilot ego not an injury? There is nothing in this to justify taxpayer dollars on an investigation. ATSB could spend a year on this to finally recommend a light on a pole, or low cost option of palm tree (illuminated of course) planted in the middle of the grassed area, or wow, a truckload of concrete.

What about the wing inspection lights. Is their policy to taxi with every light turned on in every direction as per QF?
