Being located near a train line with a direct city link can help, particularly it seems on the north shore (cf. Killara, Gordon, which have historically led price growth in previous cycles).
On the other hand being in an industrial suburb under a flight path, historically at least, has been a negative, with inner western suburbs such as Mascot having lagged through the cycle.
I expect this widening of prices to continue.
Huge day ahead for interest rate twitchers with the pending release of the third quarter inflation figures later this morning.
