The top 20 most ‘crowded’ suburbs across Australia

Where can you find the most people packed into one suburb?  According to the latest Census data, look no further than the inner Sydney suburb of Elizabeth Bay.  This suburb covers about one quarter of a square kilometre of prime Inner Sydney real estate and, according to the latest Census figures, is home to 5,093 persons which works out to be about 2 persons per 100 square metres of land.  The second most densely populated suburb in the country is right next door at Rushcutters Bay, with a comparatively sparse population density of 1.5 persons per 100 square metres.

Nineteen of Australia’s top twenty most densely populated suburbs are located in Sydney.  The one exception is Melbourne’s Southbank which ranks at number 19 in the population density stakes.

The table below shows the top 20 suburbs across Australia based on the highest population density on a rate/sqkm:

Interestingly, third on the top twenty list is the comparatively outer lying suburb of Wentworth Point which is located on the Parramatta River about 16km from the Sydney CBD.  The suburb was gazetted in 2009 and was previously part of the suburb of Homebush.   Having such a high population density outside of the inner city is quite uncommon for an Australian city (particularly outside of Sydney), however, as urban renewal projects and brownfield developments spread further away from the city centres, a greater level of population density in the middle ring suburbs is likely to become more common.

The spatial patterns of population density are generally centric to the inner city and follow the path of key transport infrastructure.  The trend is quite clear on the thematic maps below which include a 1km train station buffers overlay.  It makes sense that higher population densities will follow the established transport corridors; land along these routes is generally zoned for higher densities.  As transit oriented developments continue to gather pace I am quite certain we will see higher population densities spreading to key transport nodes located further away from the city centres.

    Hi Tim
    unfortunately your figures are a little screwed up Elizabeth Bay actually has about 1 person per 50 square metres. It looks as though you have worked on 1 square kilometre as being 1000 square metres instead of a million square metres.

      Thanks John, I’ve adjusted the commentary to accurately represent the population density over 100sqm. Thanks for your pick up. Note that the tables refer to square km’s. Tim

    Nice post, I’d like to add that… Before jumping into the stock market, assess your tolerance for risk. The stock market can be a great way to make money, but it isn’t for everyone.

    If you enter into it, you will have to take some risks and to
    some, those risks will feel quite large. If you have no tolerance for
    risk, it might be better to realize that the stock market just
    isn’t for you.

    It is certain that a few rounds of negotiation will
    be required before you settle on a price. Opt for the Real Estate Agent who has
    a government license. Whenever choosing an estate agent its
    best to do some homework regarding the agent’s registration and cross checking the same with the board.
