Solution
To answer this question, we need to consider the geographical layout of Australia, the number of houses located near the coast, and the potential impact of a 1m rise in sea levels.
-
Australia is an island continent with a significant proportion of its population living in coastal areas.
-
According to a report by the Climate Council, a 1m rise in sea levels could inundate up to 250,000 properties in Australia, including houses and apartments.

However, this is an estimate and the actual number could be higher or lower depending on a range of factors, including the exact amount of sea-level rise, the nature of coastal defenses, and future changes in population and housing.
So, based on the given choices, the closest answer would be "Up to 250,000".
