The Amateur Astronomy Foundation has some free online courses in astrophysics. One course in particular outlines what happens when a supernova wave front hits the Oord Cloud and the Kuiper Belt located in the outer reaches our solar system. The effect is clearly a disruption of dust and comets surrounding the solar system, and a heating and compression of the solar system as a whole. The compression kicks dust particles and comets from the surrounding Oord Cloud and Kuiper Belt into the central solar system.
Specifically, the result of a supernova wave front interacting with the dust in the solar system is explained. The unperturbed solar system maintains a balance between the self-gravity and the pressure from the dust that permeates out from the Sun in a sphere. When a supernova hits our solar system, it compresses these dust particles causing the self-gravity to defeat the pressure. The result is an increase in dust particles and comets intruding into the core of the solar system. This dust consists of higher elements cooked in the center of stars. Sounds pretty toxic. Maybe someone is trying to figure out how to protect humanity from radioactive particulate matter penetrating the atmosphere (Chemtrails).
Two other effects from supernova interaction with the solar system would be a heating of the core and a flattening of the solar system into a disc. Obviously we are heating up. Not much needs to be said about this other than it is a fact. The flattening of the solar system into a disc would result in bringing all the objects in the Oord Cloud and Kuiper Belt closer to us, basically. This will increase the risk of impact from comets and increase the density of radioactive dust in our general vicinity.
Due to copyright, you will have to go read the hard science materials on their website. The link starts you at the front page (as they requested), and then you navigate as follows:

Read the all of lecture 10. It is terribly scientific and specifically describes the Aussie Bloke scenario as not just highly possible, but known fact. Radioactive dust and comets intruding into our neighborhood will clearly be a major concern if our solar system encounters a supernova wave.
