You should be able to get change over shoes at most brake services. Some older brake services will bond new linings for you,but these are hard to find these days as disc brakes are used on most modern vehicles.
I would suggest you have to match the shoes to the backing plates. You can not mix and match that way. Also Al-Ko only list off-road magnets, not shoes. The difference between off-road brake assemblies and the regular ones is just the way the magnets are mounted so as not to wear as quickly in the outback road conditions.

I was told that it was more practical to just change over the complete back plate assy, rather than individual parts. When the shoes are worn out so is everything else.
Read Iana's above.
Same as a set of tyres on four wheel drives.
NEVER just one
unless a blowout or stake.In which case I normally go on ebay.
for second hand worn to my level.
Brake shoes are matched to the diameter and width of the brake drum. Some times OE shoes come riveted,some come bonded.Replacement shoes should come bonded and profiled to the drum size particularly if the braking surface of the drum has been machined.Brake shoes are not matched to backing plates but are manufactured to fit a variety of applications. When relining, units should be done in pairs and on a tandem system all four is preferable. Your drums can be measured with callipers and should be replaced if outside the recommended spec stamped on the drum. I was looking at trailer parts the other week at a rural parts outlet and the price for a complete 10"electric brake assembly with parking brake,in LH or RH was $129 and drums to suit $89.For about another $30 you can have the unit in galvanised form.Good idea if you are doing a lot of off road work. Macka has probably seen these at The Man's Toyshop in Rocky. They have one of the best ranges of trailer parts you could ever need. Remember if you are going to remove the backing plates from the end of an axle they will require centering and if this is not done,uneven braking will result.
I just did a complete brake replacement on my Tvan 10" , backing plate with everything attached , new Hubs , wheel bearings , seals the lot for about $480 .
How do you centre the backing plate , it's held by fixed studs , take the old one off , new one in exact same place .

ALKO do not differentiate between on-road and off-road models, when it comes to shoes.
The ALKO-branded 12" shoes seem much harder to locate though. The 10" shoes are readily available.
You can pickup after-market shoes to suit the 12" brakes from places like this: https://www.couplemate.com.au/trailer-parts-shop/brake-parts/electric-brake-parts/12-inch-pair-electric-brake-shoes/
Hope the info helps.

While the backing plates are supposed to be self centering they are in fact not always as I have found out on several occasions when I have had to rectify uneven braking and lockup problems for a customer.After fitting up a new backplate it is always wise to adjust the brake shoes up tight then loosen the four bolts holding the plate to the flange before retightening and then readjust shoes.If the flanges had locating pins that were an interference fit then an accurate fit would result but with the mass production these days in offshore factories there is often variance.
