alexlee and Nth Brisbanite are spot on. It's nigh on impossible to pick the bottom, or even the start of the upswing, at the time that you're in it. Growth in Brisbane is certainly slower than it has been, but I don't imagine we're going to see falls in prices.
Since different time periods have different properties in the pool anyway, I think that any difference in prices is going to be too small to be statistically significant on a monthly or even quarterly basis. ie if the median for January in a suburb was $330K and the median in July is $325K, it's likely that sampling error will outweigh the effect of the market anyway. By the time you get a sample large enough for market forces to be more statistically significant than sampling error, the time to buy would have passed.
It really doesn't matter what "the market" is doing in terms of when to buy within a 1 or 2 year period; it only matters what you can negotiate on your particular purchase. If your vendor isn't aware that prices this quarter are going to be 5% higher than last quarter (and they can't know this yet because the data isn't available, and most vendors aren't that informed anyway), then they're not going to hold out for 5% more than they would have accepted last quarter!
Find a property that you think represents a good long-term prospect, and buy it.
