treat it like a franchise, dissect australia up into areas ( i generallly use 40 as a start eg: major cities/areas like sydney and gold coast [ but they can also be split into north/s/e/w ] then in regional areas i go with areas like " northern rivers" , " southern highlands" " gippsland", "tropical north qld" which makes it clear because the government has already done it for you via their tourism dissections )
its all postcode based so there are CLEAR lines of territory.
i think we have talked about this before? but i'll dish it out here.
then use a contact form that is setup to draw from a database the lead in that area and automatically email them the contact info lik i use on my
"waterforwatercoolers dot com au " website
all you need do is sell the idea to 40 debt collectors in 40 areas and you have australia covered.

by the way ( anyone) you can contract me to set this form up for you as long as you are not in my business sectors ( which are few )
