South Australia's Independent Commissioner Against Corruption has announced it will investigate country MPs' use of an accommodation allowance over the past 10 years.

The announcement comes after three SA Liberal MPs learned they would have to repay more than $70,000 of taxpayers' money claimed for accommodation in Adelaide.

Earlier this month I commenced an investigation into the conduct of a number of members of parliament in respect of claims made by them for payment of the country members accommodation allowance.

I intend to make further enquiries in respect of all claims for the country members accommodation allowance by any member of parliament over the last 10 years.

A peak body for public health in Australia has sounded the alarm over the possibility Covid-19 related drugs and vaccines will not be shared equitably among all countries.

The Public Health Association of Australia has told a parliamentary committee the Australian government should consider mechanisms to override patents where necessary.

I don't think there are any easy answers. We really need to cultivate an environment at the global level where countries commit to sharing things equitably, where we don't have this sort of nationalism that results in bans on exports of drugs and results in countries buying up supplies of drugs in advance, and things like this that prevent equitable sharing."
