Are you serious Perth Darwin etc should not even be considered when it comes to a national flyin... This sounds terrible and i fully understand it will inflame members in outlying areas and i appologise, but realities are realities...... They should either have there own event or none at all...you cant be all things to all people ...
Those who try to be fail and fail dismally everytim unless they have huge budgets, extremely mobile participants (jet flyers with money) or inelastic demand curves.
You dont hold national events in broken hill to keep westerners happy and you dont hold rock concerts in Perth as a one off on an australian tour for a reason...
People who think we need to host these event severely west to cater for 10-15 % of australias population are a major part of the problem that will doom these events into history...
Your first and fundamental problem is a location people will attend in abbundance...everything else is secondary. By going west you not only cater for less people you make it harder for the other 90 % who will attend to actually want to go, afford to go or time to go...
Take this example...
Temora. Flying time to melb and syd is reasonable...one nights accommodation to each would yield major attendance... Similarly mailtand for syd and east coast ( bad example for melb)
Move event to say Naromine you have major flight time from syd, massive from Melb, brisbane newc gong and GC Brisbane sunny coast .... No matter people intentions , attendance drops ...
Now narromine is clearly better for SA or WA NT, but realistacally how many actually attend.. And if it was 1 hour east would it really change attendes from Perth, or NT ...no
But shift it one hour further from Syd or Melb / east coast and numbers dramatically fall....why because you add a second nights accomodation, which doubles the cost, means your away the entire weekend, need a night off work etc...that wont matter for some people, but force it on many and your numbers drop dramatically.
Trust me it on this , post grad studies in this area reveal a thing or two about elasticity of demand, barriers to entry and invisible/ visible scripts to participation...
you want numbers it needs to be a day trip or one nighter from the majority of your population...doing anything else dramatically effects participation..
Secondly people need a regular cycle and location...eg every year or second year at X location..... Doctors and lawyers with high disposable income and who are time poor will pay to travel to exotic and varied locations, but the majority of people like and are more likely to attend the same location on a regular cycle because they like predictability, known costs and known issues...
One only has to access night sat images of Australia and its pretty clear where most events need to be held... Add in CTA and its effects on RAAus pilots, its still pretty clear which areas will work and which wont...
Sorry but The rest are dreamers....if you think we should hold it on the Nullabour or in Perth, you are a very very nice considerate person, but have no concept of the laws of supply and demand , crowd dynamics, elascticity of demand or pschological scripts to attendance...
