article is right and wrong...
If you grab the usual economic data i.e. demand and supply you will quickly see (factually) there is a massive and increasing stock deficiency in NSW\QLD.
Further more population is growing both internally and through immigration which means this in balance simply accelerates.
Combine all the above factors together with the market cycle being (in NSW atleast) at the bottom, reaching the bottom or in plateau then it is easy to assume a "mother of all" booms is "theoretically" possible.
In my view the only reason why we haven't seen at least steady growth in (NSW) is sentiment. Just as is the case in stock markets it doesnt matter the PE ration or any other data etc sentiment rules supreme and governs price. This is why we see booms\crashes and not a steady even rise or fall. A steady even rise\fall would suggest logic but given the market "waits for a clear sign" e.g. for property.. falling interest rates then prices stay on hold.
This is why its easy for economists based on the market today to think "something" will happen.
The problem i see (this time round) is that there are capacity constraints built into the market. Wages have not kept pace with inflation and this will be the case if the government doesn't want inflation expectations feeding into inflation and becoming a self fulfilling prophecy and hence increase inflation.
But.. more importantly it is the lack of infrastructure that prevent the current demmand to be met with supply. Coupled with high petrol prices there is NO demmand for greenfield sites on the edges of sydney because there are no trains\transport there. Developers and end buyers are just not buying there there fore theres a perceived lack of supply and over-demmand. In reality its a case of product mismatch.. whats being demanded isnt on offer.. that is inner city infill developments (on a grand scale).
This wont happen because of NIMBY's preventing it. Theres an article in the local Baulkham Hills paper stating the governments frustration that the community is screaming for buses and trains to be brought in but each time they put forward a proposal anyone living directly on ANY route cry foul. Council buckles and nothing happens.. in a nut shell government needs to start governing for the majority and not the minority.. this is life there are some loosers... problem is right now we are happy to have all of us loose rather than a small proportion.
Now i could be wrong and urban sprawl may continue but to where Orange?
So i think economists have it wrong because they are unable to factor in the softer and harder to identify factors of affordability, capacity constraints and wages/costs. This will act as a price dampener and it is why in Sydney we are seeing strange things happening. Pyrmont\Chippendale\Darlinghurst etc all posting 15%+ growth... in short those that can keep paying higher and higher will but those that cant wont...
This is why economists are thinking theres more people staying at home longer.. etc etc i.e. simply avoiding buying a house even though they need one.
So in summary i think the article is right and wrong... it should be a boom but reality is theres a log jam to that growth in the form of affordability and capacity constraint... heaven help the first home buyer if a government solves those two issues... thats when we will have fireworks until us developers catch up
all my comments above are tempered with the following line i like to say which seems to sort things out...
"if there is enough demand for eggs even the rooster's will start laying eggs"
