Michelle's summary seems pretty right to me

Grattan on Friday: 100 days and the "adults" still have a lot of growing up to do.

It starts:

It is just 100 days on Monday since the election, but the Abbott government lacks that air of excitement that power often brings. Rather, it is staggering towards Christmas, mugged by moving from rhetoric to reality, from the disciplined order of opposition to the setbacks and unexpected challenges of office.

We will do, Abbott pledged before the election, reeling off intentions, only to find there are many things, including the core promises of repealing the carbon and mining taxes, that he can’t do, at least for the moment.

He’d run a government of no surprises, he said. Well, he has been surprised, unpleasantly – most notably by the revelations about Australian spying in Indonesia, as well as by Holden’s intended departure.

And there’s been the unsettling reminder that voters were more anxious to throw out Labor than enthusiastic about the Coalition; now they’re unimpressed by the government’s early efforts. This week’s Newspoll had the ALP leading 52-48%. Satisfaction with Abbott’s performance was 40% - it has fallen steadily from 47% in October. Opposition leader Bill Shorten’s satisfaction rating was 44% - it has risen steadily from 32% in October.
