My recording didn't work but it looks like Jo Palmer had a coughing fit or similar on tonight's Tasmanian bulletin with Peter Murphy taking over the bulletin and reading the rest of the news as well as doing his usual weather. He also included regular updates about Jo and that she'd be returning to do the updates later.
The SCTV News website has been updated and shows Jo doing the first few stories and then Pete doing others afterwards. There was a post on the Southern Cross Tasmania facebook page giving an update too. Would have been an interesting time with a possible quick ad break and a "you're up Pete!" and straight in the chair.
Wonder if EyewitnessTV managed to get it or someone else.
