There’s certainly a lot around, it’s a real sign of a big population when you start seeing groups of them hopping around in daylight (like they often are around ADFA/Russell). Sometimes I wonder how much of the burrows have ended up under the roads around there - might make for interesting subsidence issues in the future.
The shooting crews are effective, it made a very noticeable difference on City Hill when they went through there a while back (went from eaten down to roots and bark being chewed to the grass growing back). If the local population is developing resistance to the current calicivirus though the government is going to end up hard pressed trying to shoot enough rabbits to keep up with their population growth (unless we end up in drought anyway).
Diesel electrics can be very stealthy, with the potential to be even more so than nuclear subs when trying to hide (given equivalent level of technology elsewhere in the design). What they can’t do is continue being stealthy for anywhere near the time a nuclear sub can as eventually you need to come near the surface and run the diesel to recharge the batteries. Diesel electrics are also comparatively range limited - while they can travel a considerable distance nuclear subs are effectively only limited by their ability to supply the crew.
