Alot of good points raised however show me the statistics.

Actually our state has managed to invite more businesses than Virgin. Other organisations include; Boeing, Optus, IBM, Oracle amongst a huge list of other organisations relocating to Brisbane. Just check out the source below for the full listing.

The other key factor is that our state government is providing resources to those types of organisations that provide not just employment opportunities, but areas that can greatly affect humanity, ie in areas of Biotechnology and Information Technology. This is not to say that it is not being done in other states, but definately not on QLD’s same scale.

This is also being introduced into our education system which rates highly not just domestically but also internationally. Private schools for example are a lot more affordable in Brisbane than either of Sydney and Melbourne, but cannot be argued that it delievers a lesser quality of education. Our universities are regurarly voted no.1 in the country. UQ and QUT namely. So is our Business Schools, perhaps not with the same reputation as our international counterparts, but we are young and relatively new.

Also there is much more that makes a city a target for people to immigrate to. For example infrastructure, cost of living. Queensland boasts the cheapest petrol of all states, on average it also boasts cheaper shopping trolleys.
There are many reasons for the southerners to move here aside from affordability. Take for example the weather, Brisbane vs Melbourne’s four season days.

Brisbanes infrastructure is on the improve, with ugrades in and around the city, this includes City Bypasses, quick routes to the city, a city train link to the airport, links to the Gold and Sunshine coasts. Our roads boast less trafic congestion and public transport is being improved to be more widely accessable.

After all we have two great sporting teams up here to support, in the League the mighty maroons and for the aerial ping pong fans the mighty lions. what more could you want [].

But seriously these stack up as excellent reasons for continued growth. Of course there will be a correction, but in my Humble opinion it will not be because of interest changes, but perhaps a lack of demand in the mid term.
