We have some cold starts ahead. There's a forecast low of minus 1 each morning until Wednesday, and today packs a nasty combination of early frost, cloud, a 60% chance of a late shower and a measly high of 12 degrees. Bring on spring!

Here's the local headlines:

Fears about the state of youth detention centre Bimberi and incidents at Canberra's Alexander Maconochie Centre are bubbling away. Now ACT Human Rights Commission Dr Helen Watchirs says Canberra needs a wide-ranging audit of the oversight of its prisons and other 'places of detention' to ensure the city can meet protocols under the UN's Convention Against Torture.

She said it should identify the gaps in oversight of all detention facilities and the practical changes needed, as a "first step" towards meeting the Optional Protocols under the Convention.

It should also lead to a single ACT-wide body to protect the human rights of detainees in all facilities, ranging from prisons to mental health units, disability, aged and child protection facilities.

An ACT Policing officer misused the Australian Federal Police database, helped his mate get a job with the AFP, looked up information for his criminal friends and hunted for an apartment with his official email, an internal conduct report shows.

ACT Policing and AFP officers face two years' jail for accessing information off the Police Real-Time Management Information System (PROMIS) not in line with their official duties, and are also required to only use their AFP email for official duties.

But over a period of ten years, one ACT Policing officer accessed PROMIS multiple times to look up information for their friends or pass on police information.

Hot-desking is all the rage in private sector companies, even if many of their workers are not fans of packing their belongings into a locker at the end of each day.

The trend is hitting the Tax Office, who are making staff leave their familiar desks behind at two offices.

But the plan has met fierce resistance after a union threatened to take its fight against the arrival of hot-desking to the Fair Work Commission.

Many opponents of a same-sex marriage plebiscite said they feared it could lead to some damaging public debate. The leader of Canberra's Catholics calls the postal plebiscite a test of national maturity on this front, but predicts Australians will vote against a change to the law.

Canberra and Goulburn Archbishop Christopher Prowse has encouraged priests in the diocese to make the case for a 'no' vote to parishioners, calling on all Canberrans, including newly arrived migrants, to enrol to take part in the survey.

Tom McIlroy spoke to the archbishop.

The cost of the Mr Fluffy clean-up has dropped about 25 per cent with reduced demolition costs and a rising property market.

The scheme should now cost ACT taxpayers $307 million, or about $100 million less than the initial $400 million-plus estimate.

Of a total of 510 remediated blocks released for sale, 392 have sold and a number are under offer.
