Australia's Olympic athletics team spent several hours in lockdown at a pre-Games training camp in Cairns this weekend after a staff member returned an inconclusive Covid-19 test. Chef de mission Ian Chesterman said the person had tested negative in Melbourne before travelling on Thursday to join the team in Cairns, where a further test in Cairns produced the inconclusive result.

All athletes were confined to their rooms for several hours until Saturday evening, though further tests are expected to confirm the person is not infected and a warm-up meet planned for Sunday is going ahead.

In case you missed it, Minister for Immigration, Alex Hawke, has announced this weekend that supermarkets in states and territories subject to Covid-19 lockdowns will be able to employe international students for more than the 40 hours/ fortnight that normally applies.

The reason for the change, according to Hawke, is to help supermarkets stay open and cope with high customer demand, even when employees are required to self-isolate.
