A vet told me the brown ticks are not a problem, it's the gun-metal grey ticks that can cause paralysis and death in small dogs (and aren't very healthy for small children either). The paralysis toxin doesn't seem to be present at all times of the year though. I seem to recall summer-autumn is a bad time, but whether this is because the ticks and dogs are active then or because the toxin levels are high at that time is something I don't know. From what I've seen of dogs that have died from tick paralysis, it happens in the summer-autumn, the back legs start to go wobbly and it's a few days later that the dog is no more. Removal of ticks and vet support at the leg-wobble stage can save the dog.
I've not heard of Tassie ticks carrying specific diseases the way Queensland ticks can carry typhus, but anything that pierces your skin can introduce infection-causing bacteria.
