A growing Covid-19 cluster in Brisbane has forced the Australian city back into lockdown

The Queensland capital recorded four new community cases overnight, almost doubling its outbreak.

Residents will be put under stay-at-home orders for three days.

There are fears the virus has spread, after revelations a case visited Gladstone, another city in the state.

Premier Annastacia Palaszczuk says she knows lockdown will disrupt people's lives.

But she says they've tackled outbreaks before - and if everyone does the right thing - they'll do it again.
