Ideally, I'd wait until there's zero community transmission before reopening borders. But I think the risk of a substantial outbreak is low.
Tooth fossils from NSW have confirmed sauropods weren't exclusive to Queensland. They're also providing a first look at how these colossal dinosaurs fed from Australia's land.
There are two interesting points about Australia's travel bubble with New Zealand. It only includes NSW and the NT. And for now, it's only one way.
Overall, Victoria’s roadmap is good. It identifies the right goal, provides explicit criteria for when restrictions might be lifted, and involves mostly appropriate restrictions.

The fate of deer carcasses is a crucial consideration in monitoring the success of future culling.
The NSW government has announced plans to remove feral deer from its list of official game animals. With careful monitoring, the resulting free-for-all could help curb their booming numbers.
The recall of several milk brands due to the possible presence of E. Coli is the second milk recall to affect Victoria and New South Wales this month.

A NSW court's decision to rule out a coalmine on the basis of climate change could signal a turning of the tide in an arena where environmental litigants have previously struggled to gain traction.
Sydney’s iconic beaches are not yet part of a marine park.
The New South Wales government has turned its back on plans to create sanctuary zones covering 2.4% of waters around Sydney, despite evidence that these 'no-take' areas are crucial for protecting fish.
We need female role models in the NSW physics syllabus to normalise women in physics and encourage their engagement and further study.
The new physics syllabus for year 11 and 12 students in NSW contains no mention of specific women who have contributed to the field, nor their work.
