Construction, reaction, rotation
Brisbane's apartment construction cycle is clearly on its last legs now, with commencements falling away sharply.
But all those new people arriving from down south or overseas also need supermarkets, shops and shopping malls, and schools, and six star hotels, and service stations, and sausage sizzles.
This we're now moving into a different phase, with a number of major infrastructure projects and transport upgrades getting underway.
Less well publicised, there's also some significant investment in commercial development around the traps.
And, yes, that includes the odd new Bunnings.
In the words of the old infomercials, Brisbane is a city on the move.
