This form of preference-dealing is highly overemphasised. HTV cards only matter if you can get them into the hands of a reasonable proportion of voters, and the reality is that only the major parties (in Australia, to some extent this includes the Greens) have the base of election volunteers available to widely staff polling booths handing out HTVs. The preferences of minor party voters tend to scatter pretty randomly.
