You can form government if you can win a vote of confidence in the house. So some other parties might give them a vote of confidence and they can form government, but any individual piece of legislation the introduce could fail. Australia has had two minority governments (technically only one) in the last decade and I consider it a good thing, all the stupidest legislation gets defeated.
