another advantage of an asx listing is that you get Wall Street Reporter covering your company (inc an interview on their site):
eg
View Resources Ltd ("View") is a junior mineral exploration company listed on the Australian Stock Exchange Limited (ASX Code: VRE).View recently announced a conditional agreement to purchase the Carnilya Hill Mine and mining tenements near Kambalda.
An analogy:
To me you've got AIM (a small duckpond infested with shorters), with little global standing.
and then the tsx and asx; two bigger ponds where the deals get done, and where the fish are all fat carp (i.e. those with a chunky mkt cap)
