Is the Liberal Party of Australia the most conservative of all of the present political parties of Australia?
Of 'significant' parties, the National Party tends to be slightly more conservative than the Liberal Party, but they normally operate in coalition - differences are minor.
Of less significant parties, Family First has one Federal Senator, and a few members of State Parliaments - they are a socially conservative party, and closely linked to some Christian groups. The Christian Democrats have one member of a state Parliament.
Basically the Liberals are the only conservative party that can realistically give us a Prime Minister, the Liberals and Nationals the only conservative parties that can give us state Premiers. None of the others can do more than put a few people into Parliaments.
No, it is moderate/conservative. But it is in a coalition with the National Party which is very conservative.
