IMO it's worth calling Volvo Lindfield to see if they can help.
The chassis numbers are broadly sequential, as far as I can tell, but they have different ranges for the different variants
If you compare to the total units figures on Volvo Club UK, you can sort of spitball how early or late in the model year yours is.
Interesting discussion .
I have done a bit of research on this also and tracked many 240 VINs for sale over the years just to get a picture of the provenance. I have owned seven 240's over time , 3 wagons /4 sedans plus other models.
I believe the 240 are genius and so underrated in every aspect.
My car MY 93 240 made Oct 92 /complied Dec 92 and I have been told by Volvo it landed in the last MAIN batch of cars destined for OZ in December 92 . Others dribbled in based on final orders to customers built slightly later on the production line I was told .
A number of the Oct 92 batch sat in bond /customs not released for a while until cleared in 93.
I have seen a compliance plate as late as July 93 on a 240 wagon .
Also some country dealers had floor stock for a year or so and were not registered until late 93 , I have seen a 240 wagon first registered in 94 but still an Oct 92 built, being a 93 of course .
An ex Volvo dealer informed me that Volvo Aust pushed stock on to dealers as the model wound down ,interesting manufacturers still do this today.
OZ was a small market and I was informed primary focus was US/Japan and other markets in the final stages with special models like the Classic ( numbered )/Torslanda etc the final priority.
As always i I think it comes down to the VIN , my car was made 427 after the 240 sedan you posted above .
I found another car with a VIN 199 after mine first registered June 93 .
My car was first registered 11/6/1993 by REG Hunt Volvo Elsternwick in Melbourne with 11 klms .
I have all the delivery papers and purchase documents.
As to which was the last Volvo 240 sold in Australia is may be a moot point ,VIN numbers I believe reflect the manufacture cycle and birth . Last one sold could be a good accolade all the same ,if it could be proven.
Interesting perspective all the same probably one to be debated at the next Volvo meet .
I hope my research offers something to a assist

Another interesting discussion that I've been trying to get to the bottom of is I've seen a number of MY93 240 wagons badged 240GLE with leather, power windows, plush velour door cards, and power heated exterior mirrors. I can't find any record of 240GLE being offered in MY93 in Australia, but I'm convinced they were some sort of a special/late batch. Our 93 240 wagon (EV conversion) is one of these cars, and a mate owned another one, and I've seen at least a 3rd and 4th one on Car sales at one time or another. Would love to be able to find some documentation proving the existance of a MY93 240GLE wagon in Australia if anyone has it.
I remember SVM Lindfield still had some new dark green 240 sedans for sale in April 1994. My mum bought a 2nd hand 1990 240 from them at that time and they mentioned they still had some new 240s left. They were the last stock.
JaanPP Good memory! My wagon is dark green. Maybe I should, pull my finger out and, get in touch with SVM.
With respect to the chassis numbers being sequential ... apparently for Holden, a chassis number was assigned as part of the system scheduling the run down the production line, but cars didn't run off the end of the line in numerical sequence. I don't know the reason why, but I think production lines these days may be more flexible than they used to be, for example I think in the 90's they'd have had to run batches of the same colour at the same time whereas now I think the lines can switch between colours for sequential cars.
So unless you're dead certain that the numbers were ASSIGNED in the same order as they rolled off the line, the VIN might not be the be-all and end-all.
Ramrodfunk yep they might know, but it’s a while back now. Did you buy your wagon from them new?
JaanPP No, I bought my wagon from a man in Bellingen, NSW. I only know it was sold from SVM is the faded sticker on the rear window.
Forg Ok that makes sense. Yeah the vin seems to only "muddy the waters".
It would make sense to, especially for paint, have cars detoured to a holding area till they could be painted in batches.
There is another numbered plate on the panel near the hood latch. I asked people about this plate but have not got definitive answer.
It would be great if Volvo would hand over the production and shipping records if they had them!
Cheers

Volvo Heritage in Sweden retains some of the build sheets for various models - I got some info from them sourced from the build sheet for my 1800ES.
AFAIK Volvo Australia don't have / kept any records of the cars built up from CKD kits in Melbourne.
Also AFAIK the last of the RHD 240s came out of the Torslanda plant.
I read somewhere (forgot where) that Torslanda was the last plant to build 240s, as Kalmar was doing the 900s and they wanted to make way at Torslanda for the 8fitty. 
Happy to be corrected on that since I can't recall the source.
Ramrodfunk do you know what the original number plate was?
JaanPP No, I don't know. No log books.
Ramrodfunk The plate near the hood/bonnet latch is the body number…similar to on some earlier cars. Typically the body number (at least on the 1800s) was close in sequence to the VIN, but that may not be the case on 240s. I think it is just another way for them to keep track of the bodies through the build process. I suspect they may have put the body number plate on cars before the VIN was stamped into the pillar as they typically built some extra bodies just in case one got damaged in process - it could then be re-assigned prior to VIN stamping.
