Yes, this is true but the drive from China is relentless! The chinese government want to migrate 80,000 people a week from rural into urban environments. Oz is resource rich and will need to keep feeding this growing giant...
I tend to be a sceptic when it comes to 'this time it's different' theories. Will Chinese growth continue at this rate forever? 80,000 people a week is 40m a year. Sounds like a lot until you remember MOST of China's 1bn+ population is in rural areas, most of them illiterate peasants. Can every illiterate peasant suddenly become car buying middle class workers?
Is the Chinese system robust enough to accept all these migrants? Cities want the workers but don't want the hassle of providing services and housing for them. The old 'domicile' rules still prevent true freedom of movement. Will corruption and lack of political freedom cause backlashes in the hinterland (lots more peasant uprisings now compared to the past, often because local governments are seizing rural land for building). Are regional party cadres building useless infrastructure just to enhance their own prestige (US companies did it in the 70's and 80's. I'm betting the Chinese are worse)? Will protection of state owned enterprises cause bad debt blowups a la Japan in the 80's? What happens if China has a temporary stumble, just as mining capacity comes on-line all around the world? If Oz is building more mines, surely the Brazillians, etc are as well.
I'm just saying China has its issues, and those might cause it to stumble in the short term. Long term China will industrialise, but I wouldn't want to have just bought WA property and China has a 5-10 year recession. Just because the long term trend for commodities is up (which I believe in) doesn't mean growth is consistent year on year. Watch out for lumps.
I still say a safer long term plan is to find the city with the best combination of affordability, yield and -ve market sentiment and buy there. When that becomes hot, buy elsewhere. Perth would score bad marks on all three. Sydney has -ve sentiment but is not affordable and has low yields.
Remember when in the 80's Japan was going to take over the world? Or even earlier when the Bundesbank was going to dominate? When the NASDAQ hit 5000 and old economy stocks (and old economies like Australia) were going to be sidelined? Chinese supremacy is not guaranteed.
