Western Australia - Pole Shift

Last night I had a dream. An old wise looking white haired man showed me a map of Australia. There was a curved line drawn on the map sectioning off most of Western Australia. My attention then was bought to the north and south poles. I was aware that it was in relation to a possible future polar shift. It was indicated that Western Australia would be covered in water. Queensland seemed to be ok.
Then in another part of the dream I was experiencing something catastrophic. Everything crumbling around us. We were among very few who survived. I have in the past read of information like this, so whether it was just recalling information or future insight, regardless, for me I wouldn't be living in Western Australia.
