Some  people  argue  that  the  per  vote  subsidy  is  fairer  for  small  parties  because   (of  an  assumption)  that  small  party  supporters  are  poorer.

In  reality  because  of  the  vote  percentage  cut-off  subsidies  actually  discriminate  against  the  smallest  parties.  Contributors  to  all  registered  parties  get  a  tax  benefit  even  if  that  party  is  the  Marxist-Lenenist  Party  or  the  Libertarian  Party.

The  vote  subsidy  favours  existing  parties  and  suppresses  the  emergence  of  new  parties.  It  is  no  surprise  that  the  smaller  opposition  parties  want  them.
