In the days after the worst mass shooting in Australia since Port Arthur, a wave of misinformation spread across social media.

Use of private providers, poor training and inadequate regulation mean obtaining care has become a ‘wild west’

When Leigh White remembers her brother Ryan, she thinks of a boy of extraordinary ability who “won five scholarships at 11” including a coveted place at Bancroft’s, a private school in London. He was, she said, “super bright, witty, personable, generous and kind”.

Ryan killed himself on 12 May 2024. A report written after his death acknowledged significant shortcomings in the support he received while seeking help for attention deficit hyperactivity disorder.

A light but filling no-bechamel souffle with a zingy citrus salad to add a sharp burst of flavour and colour

There is a skill in not wasting food and it’s all about good, old-fashioned housekeeping. If you learn how to store ingredients properly (cool, dark places are handy for spuds, for example) and keep tabs on what’s in your fridge/freezer, you can use everything up before it goes off – and make delicious things in the process. This golden, cheese-crusted souffle uses up the celeriac and spuds left after the festive season, plus any odds and ends of cheeses. It is spectacularly good, especially paired with a sparkling citrus salad.
