The answer of course is yes, but check out these numbers to get an idea of just how much potential there still is:
There are currently estimated to be around
40,000 employment sites in the US. The US has a poulation of around 304,000,000 meaning there is
1 job site for every 7600 people in the US.
Applying the same ratios to Asia, Australia and New Zealand we get the following:
Australia
Population 21,000,000 - so if we had a job board for every 7600 people
we should have 2763 sites.
Asia
Population 373,000,000,000 therefore >
49,000,000 employment sites
New Zealand
Population 4,500,000 therefore
592 employment sites.
I don't want to hear 101 reasons from the big job board players about why these stats don't hold up. My point is simply this:
If you assume Australia is a similar market to the US (albeit obviously smaller) and experiences similar demographics, employment conditions, internet connectivity etc, then statistically speaking Australia can support more than 2700 job boards. By our estimations there are currently less than 150 job boards in Australia.
Can we support more job boards in Australia? Heck yes.
