The only extra thing I really should get is a LASER pointer (I assume that is what people are referring to when they mention Red Dot) to assist with aiming extreme telephotos.
The camera shops I have looked at don't seem to stock them, and the main gun shop in Adelaide only has ridiculously expensive ones. The Pentax one Barondla has looks good and is very cheap, but I suspect they all need a hot shoe adaptor as well, as I guess they are designed for firearm sight rails.
Any advice out there as to what to get, and where?
Hi Sandy,
No it's not a Laser Pointer -- A Red Dot Sight Is, as you later mentioned, a gunsight, and does not project a laser beam on the subject. It projects a tight beam onto a see-through screen, and you superimpose that bright point on the subject.
You do need to mount it, but it really doesn't need to go into the hotshoe, though that's probably the most convenient. The sight does not have to be minute of angle accurate, it just has to get your subject into your viewfinder, so you can conceivably mount it on the lens hood with a Velcro strap or heavy duty rubber band.
I've got an early model Phtosolve Xtend a Sight, and this is the most commonly used hotshoe adapter I've seen, but I have seen others. . .

I searched AU Ebay for "red dot sight" and am including two links to auctions to illustrate the two most common configurations of RDS, call them the tube type and screen type. I'm not endorsing either specific product, just using them for illustration.

There were also laser sights in the results that project a beam to be placed on the target, and this is not what you want -- you should not aim lasers at living things as this would be potentially dangerous to your subjects.
Crosman and Daisy also make them for air/bb guns -- they're very lightweight, but cheaply constructed -- but they do work for this purpose.
If you're a DIYer, you could probably make a flash shoe mount from a flash shoe to 1/4-20 adapter and a long Weaver riflescope base, or if you have a flash bracket, you could mount a Weaver base on it, then mount the RDS on the Weaver rail.
