Well, we already have one in Melbourne, but my construction boom prediction was for Sydney to kick off by the end of this year, and in fact the wheels are already in motion...

A gradual beginning, but this is just the start. No miracle needed at all, in the same way no miracle was needed for the Melbourne construction boom. All it needs is the right government policy, but I'm sure a money saving expert like yourself must know that.
I agree with you that there is potential for a construction boom in Sydney but it will depend on O'Farrels response to a weakening construction sector.
If the economy gets weaker it is possible the state gov in NSW will further cut their losses and increase greenfield development which was one of his election commitments, going to 50/50 rather than 70/30, i.e. Labor had only 30% of new devel targetted at the fringe (as per the link you provided).
The big one though reducing developer levies has only been tweaked at this stage. The automatic rise Labor had set it at has been passed over by Ofarrel but this is chicken feed compared to if he pares tham back.
It is obscene the amount they charge in Sydney and on the central coast / south coast. It is at the ridiculous situation now that land procurement is now a tiny cost compared to government levies state, federal (GST) and local. OF course less houses are built when this situation happens.
If they roll these back construction will boom and go on booming at lower prices as the cost base is reduced, I don't know this points to higher prices for homes however, only lower once the initial activity spike is finished and the homes are built, could be a few years for this to happen though.
It is possible though that understanding this they go with some form of grant on all homes trying to lift prices rather than push costs down to get construction happening. In the past decade they have opted for the former but prior to that the latter was common and resulted in construction activity but not the price rises associated with urban consolidation policies that have to be wound back if construction is to boom without a rise in prices.
Melbournes weakness IMO is a result of the progressive advantages they gave to new builds with extra grants for new builds only to FHBrs. They were building near twice as many homes as Sydney over the last couple of years, Melbourne so was always going to be the poorer performer once that activity spike washed through.
Would not surprise me if in 6 months Melbourne is listed along with Perth and Brisbane but Sydney, Central and South coasts I do agree are different just due to the complete incompetance of the just ousted Labor government mostly. They could not organise a chook raffle let alone make a conducive enviroment for sustainable development. O'Farrel it seems and his government are different.
