It is possible to vote no confidence, it's generally called a "spoilt vote".
Whowever you vote for the Governemnt always wins.
This time I expect that there will be a record low turn out, only signed up party member will actually vote FOR anyone, the rest who vote will either protest vote or go for the least worst option.
We will end up with a Goverment voted for by 20ish% of the population, yet they will claim a great victory.
There will be more schemes to get people out to vote, postal, internet, polling booths in supermarkets etc.
What the politicians need to realise is that people are not too idle to vote, they want someone to vote FOR, someone to WIN, instead of getting a government of the least worse losers.
I recomend a record turn out and "spoilt votes", lets vote for US, not THEM, lets remind the politicians that they are there to serve US, not tell us what to do and charge us for the privelage!
