The OSCARs also include several new safety features. The doors on older rolling stock such as V Sets and G Sets are all unlocked at every station (even short platforms). V Sets have doors which must be slid open for alighting/boarding and G Sets have push buttons. However on the H Set, the guard is able to select the number of doors to be opened at a station. This feature is aimed at preventing incidents where passengers may fall from the carriage when stopped at a short platform.

I'm not sure how true it is, but if so, why couldn't EDi/Bombardier incorporate this in their SMU/IMUs for Tennsyon, (to some extent Traveston) and Rosewood services.

This technology (sometimes used with GPS or other positioning systems for accuracy) could be used, but would not solve the problem with 6-car units at 3-car platforms as passengers may not be able to transfer between units due to lack of corridor. The train could stop with part of both units in the platform, but signalling or track infrastructure may prevent this at some locations.

I must admit I never knew that it was possible on a V Set to walk out the door from a carriage not on the platform at a short platform station.  That's pretty shocking.

But it seems relatively easy to require pax for the stations between Ipswich and Rosewood to use the front 3 cars.  Central Coast/Newcastle commuters have been doing it for decades.

The train could stop with part of both units in the platform, but signalling or track infrastructure may prevent this at some locations.
The 11:06pm Rosewood through train (ex-Central) is regularly 6 cars with the back 3 cars locked.  If they can do it for that train, why not other trains, unless, of course, it causes a problem in the other direction.

I doubt it would be worth the investment for the sake of using Tennnyson for more than the four or five Mon-Fri services it receives (mostly for the benefit of school students), when they money could probably be better spent elsewhere.

But abolishing the Rosewood line interchange crapulence seems to be a pretty positive thing, doesn't it?  I suppose that the same thing applies to the Nambour line on weekends.

If your scenario works fine, then there is no need to spend money on selective door opening. Selective door opening is only useful/required if part a unit is berthed and another part of the same unit (connected via a gangway) is not berthed.
