E.g. When comparing their positions in the cycle like for like (so not Sydney post-boom and Brisbane pre-boom), Melbourne is generally 90% of Sydney prices, Brisbane is 75% of Sydney etc. (numbers aren't correct as I don't have them on me right now but you get my point). Do you see this general ratio holding true for the medium to longer terms? What would it take for there to be a significant and sustainable change in the differential? My thoughts - they will remain roughly the same. If I'm not mistaken, the only significant change in recent memory was Perth due to the mining boom. Although one could argue whether this will remain for the longer term. The Perth anomaly aside, it almost seems like things are going like clockwork - Sydney boomed, then Melboune, and now we're seeing movement in Brisbane. So basically, what would it take for this cycle / balance to change in a meaningful way? Would appreciate your thoughts on this.
